Mukul Gandhi resolved XALANJ-2754.
----------------------------------
Resolution: Fixed
I'm resolving this jira issue as fixed. The fix for this issue has been
committed to Xalan-J dev repos branch xalan-j_xslt3.0.
> parse-json handles only JSON maps and objects but not the primitive values
> string, number, boolean nor the null value

> Project: XalanJ2
> Issue Type: Bug
> Security Level: No security risk; visible to anyone(Ordinary problems in
> Xalan projects. Anybody can view the issue.)
> Components: Xalan, XPath

> This is a bug report on the XSLT 3.0 development branch of Xalan Java.
> I have tested the newly introduced parse-json function on all sorts of
> allowed input and it appears the implementation in Xalan fails to recognize a
> simple JSON string, number, boolean and the null value.
>
> Test case is:
