Question
I'm using OXygen XML Developer 15 to run a XML file validation against schematron. I'm getting errors on the system function "matches" on lines such as the following

Russian <assert test="matches(cda:languageCode/@code,'(([a-z]{2})(\-[A-Z]{2})?)')">
I searched for answers on the Internet and found this posting indicating it's an oXygen issue. But, the posting was like 6 years ago. I can't believe the problem still exists. Or is there something I'm missing here.
Even though I really like oXygen, but I don't have to use it. So if I can not resolve this issue, can somebody recommend an alternative XML tool that can do schematron validation?
The following is the entirety of my schematron:

Solution
The matches function is not available in XPath 1.0 which will be used by default for your Schematron file, it is defined in XPath 2.0, see
http://www.w3.org/TR/xpath-functions/#func-matches
If you use ISO Schematron you just need to set queryBinding="xslt2" on the root element and then XPath 2.0 functions will be recognized automatically.
