You use number streams to coordinate numbering for those elements whose occurrences in your document should be numbered sequentially, or should appear with a constant prefix or suffix (or both). As a convention, the name of any number stream should end in Stream; the DITA2Go Configuration Manager relies on this convention.
These are the default stream names defined in format components configuration templates:
You can add names for other number streams of your own, and you can change the default names. However, if you change a default name, you must change it in every place the name is referenced.
If you add your own number streams, you must define their properties. Table 8-2 lists the available properties and the values you can assign to those properties.
The value for symbols can consist of more than one character. If more are needed than are listed here, they continue with an increasing number of the last symbol listed. So if you use the default, a single asterisk, the sequence is *, **, ***, ****, and so forth. Symbols can be <u+NNNN/> for a Unicode character, where NNNN is the hexadecimal code point, as in <u+2020/> for a dagger.
For example (these are default definitions):
[ChapterStream]
help = Number stream for chapters
id = C
counters = 10
counter types = Num
[AppendixStream]
help = Number stream for appendixes
id = A
counters = 10
counter types = UCAlpha Num
repeat = last
[List1Stream]
help = Number stream for tier 1 ordered lists
id = L
counters = 3
counter types = Num LCAlpha LCRom
