IMHO, rules should never give us less freedom.. Can't it be the exception that confirms the rule ? Do we have to live without a _() documentation just for historical reasons ? Maybe we can break rules for one time.. What will happen if we add _.xml ?
file names are created from xml node IDs
some tools do not like '_' in node IDs, thats why we use '-' instead
and while _.xml and -.xml are valid filenames i'm not sure about
'-' being a valid node ID
XML spec:
| Validity constraint: ID
|
| Values of type ID must match the Name production. [...]
The Name production:
Letter ::= BaseChar | Ideographic
NameChar ::= Letter | Digit | '.' | '-' | '_' | ':' |
CombiningChar | Extender
Name ::= (Letter | '_' | ':') (NameChar)*
I am not going to copy BaseChar and Ideographic here... I assume from this spec that the XML spec does not allow us to have '-' as the first char of an ID. Unless '-' is part of BaseChar or Ideographic... It is not easy to find this out from the spec (these two have an ugly definition).
