Hi everyone, is that xsd validator cannot validate an xml schema with an
xpath having character [ or ] ? I have this question because when I
validate a schema with xpath having predicates which are embedded in
square brackets (like the following), I have the problem. In the contrary,
I don't have. If yes, is there any way to introduce an xpath with
predicates without having problems in validating?
Thanks in advance.
Toan.

Toan,

No, only restricted XPaths are allowed. See section 3.11.6 of the
specification for what's valid...
