<Now you can get confused – and please tell me about it.>
This is an X+ glossary, requested by Lycanis while he was learning X+ (at my pleading
). It includes a list of the components of X+, small and great. Each of the items on the list will be a link, to a post with an entry on that part of X+. There will be a short definition, for reference, of each of the items, by its link. The entry will include a fuller explanation (those will be added as I have the time to write them), and different examples of syntax. I would like some help on writing the explanations...I need to know what other people need to know. So if anyone is wanting to learn X+, I would appreciate it if I could help you. 
If anyone has any questions (or comments) about any of the posts in this glossary, then please reply in this thread.
Tag
The Tag is the part of the attribute which deals with the attribute as an entity. It comes before the beginning delimiter of the attribute, and can consist of any number of Titles, Aliases, and Labels.
-Title
The Title of an attribute is intended to show what specific area or part or group or aspect of the parent attribute is being described within the attribute's confines. It is the first in the order of the parts of a Tag.
-Alias
The Alias of an attribute is intended to give a handle to that specific attribute which is unique from all the other attributes, so it can be referred to. It does not change the essence of an attribute in any way. It is the second in the order of the parts of a Tag, and is always preceded by a colon (:).
- -referencing an Alias
It can be referenced to inside an element, and it is the shortcut equivalent of placing the contents of the attribute into the element. It is delimited by backslashes (\).
It can be referenced to in a Title. It means that the context of the attribute with the alias is placed around the attribute it is referenced in. It is delimited by backslashes (\).
-Label
The Label of an attribute is a part of the Tag which deals with how the attribute affects its sibling attributes. It is comprised of an element or several elements. It is the third in the order of the parts of a Tag, and is always preceded by a splat (*).
The Attributes
An Attribute is: a container made of syntax to help interpret the metaphors inside it and the surrounding attributes; and the metaphors it contains. The Attributes are these:
-Xmap
This is not always included among the list of attribute types because it has several dissimilarities with the plurality of them. However it functions like one in a basic way. It includes the whole of the Xmap, and has no delimiters, and the only part of the Tag allowed (at this time; we have not discussed this) is the Title. It is placed at the beginning of the Xmap.
-Aspect
The Aspect is meant to divide the separate, overarching aspects of the subject from each other. It is delimited by curly brackets ({ }).
-Class
A Class is meant to define various components of the whole aspect. It is delimited by square brackets ([ ]).
-Characteristic
A Characteristic is for separating out small parts and parcels, or groups, of the parent attribute. It is delimited by parenthesis (( )).
-Element
An Element is for containing the metaphors themselves. It is delimited by angled brackets (< >).
Special Functions:
-Keywords
Keywords are words which we have taken and given a specific meaning to within the context of Xmapping. They are always written in caps when used with this meaning. They (at this time) consist of: FACET LAYER ANGLE SUBTRACT ADD INTERSECT REPLACE CONCRETE ABSTRACT and ALLEGORICAL.
- -FACET
FACET is a word which can be used as a title. It is a generic name for an attribute when the title is too amorphous to be expressed in a word. (However you can also simply skip the title with a similar effect.)
- -LAYER
LAYER is a title which tells how easily the attribute is seen or perceived – how deep the attribute is. The 'LAYER1' is the layer first seen, 'LAYER2' is next, and so on.
- -ANGLE
ANGLE is a title which means that the attribute below is the subject from a certain perspective. It also can be numbered to describe several different perspectives: 'ANGLE1' ANGLE2' etc.
- -SUBTRACT
SUBTRACT was made specifically for Labels. It specifies that the attribute subtracts the essence of its contents from its sibling attributes.
- -ADD
ADD was made specifically for Labels. It specifies that the contents of the attribute add to those of its sibling attributes. It is the default Label, the assumed Label when no label is specified and the context does not make it otherwise intuitively, for the higher attributes than elements.
- -INTERSECT
INTERSECT was made specifically for Labels. It specifies that the essence of the attribute and those of its sibling attributes contribute only the essence that they share to the parent attribute. It is the default Label, the assumed Label when no label is specified and the context does not make it otherwise intuitively, for elements.
- -REPLACE
REPLACE was made specifically for Labels. It specifies that the attribute contributes nothing to its sibling attributes.
- -CONCRETE
CONCRETE was made specifically for inside of an element. It means that the metaphor is a directly correlating metaphor.
- -ABSTRACT
ABSTRACT was made specifically for inside of an element. It means that the metaphor is a metaphor of essence.
- -ALLEGORICAL
ALLEGORICAL was made specifically for inside of an element. It means that the metaphor is a metaphor of meaning.
-Special characters
Special characters are characters which have a new function when used in the context of an Xmap. They (at this time) consist of: slashes (/) dashes (–) and carats (^).
- -Slashes
A slash is used to separate two bits of a metaphor.
- -Dashes
A dash is a shortcut to nest a single element within another element. The second tier element goes to the right of the first tier element, and so on.
- -Pipes
A pipe is a way to show whether a dash or a slash is done first. It encloses the bits and the character that take precedence.
- -Carets
A caret is a divider between multiple uses of the pieces of the Tag.
Random:
-Note
A Note is a way to speak to the reader of your Xmap about the Xmap. It is delimited by pounds. The special characters revert to their normal use inside a note.
-Escape
An Escape is a way to use special characters and keywords within an X without their unique meanings. You enclose the sequence you wish to escape in quotation marks.
Terms and definitions:
-Tiers
A Tier is the depth that an attribute is nested within itself. A second-tier Class is a Class inside a Class. A fourth-tier Aspect is an Aspect within an Aspect within an Aspect within an Aspect.
-Bits
A Bit is a single metaphor or piece of a metaphor – the content on either side of a dash are separate Bits, the content in an element with no special characters is a Bit, the metaphors that are nested into each other with dashes are separate Bits.
-Parent Attributes
A parent attribute is the attribute which directly contains the attribute being spoken of.
-Child Attributes
A child attribute is an attribute contained within the attribute being spoken of.
-Sibling Attributes
A sibling attribute is an attribute which is a child attribute of the parent attribute of the attribute being spoken of.
-External reference
An external reference is a metaphor used which is referring to something supposed to be understood by the audience – a reference to a character in a book, a geographical place, etc..
