Hello,
There is an absFilePatch type in docs/schemas/basictypes.rng rng schema:
<define name="absFilePath">
<data type="string">
<param
name="pattern">/[a-zA-Z0-9_\.\+\-\\&"'<>/%,:]+</param>
</data>
</define>
There are quite few symbols in this set of the ones, which linux allows to
have in file paths. For example spaces or curly braces are not allowed.
There are a lot of elements of this type in other rng schems, for example:
[snip]
So the question is, where did this path pattern come from? Is it
possible to
use file paths with another symbols or there will be some problems?
I think this regex pattern is a bit of a misguided attempt to perform
semantic validation on the XML content. I'd probably be inclined to
simplify it to '/.*' and just delegate all other validation to drivers
as they desire.
