EXtensions...xml processing

you always faced with "missing features" if you working with existing standards.

two reasons for that:

1. the feature is specific to your domain or solution
2. the feature is common but for some reasons (and there might be good ones) didn't get it in the existing standard

for the second case common EXtensions might be the area you looking for. in the xml domain the following projects trying to define "standard extensions". this means that extending an existing standard out of the scope of the standard process itself but without loosing the portability of applicaton using the extensions.

projects

• XPath
  => EXPath
• XSLT 1.0
  => EXSLT
• XSLT 2.0
  => see discussion about EXSLT 2.0
  
• XQuery
  => EXQuery
• XProc
  => EXProc

beside EXSLT which is well-known and already produced a sufficient amount of output all other EX communities are brand new and therefore doesn't provide any output so far.
