We are having this issue while compiling an XSL file. gml:id is an attribute in the XSL file. Here is the stacktrace:

java.lang.NullPointerException: Internal error: expression ("gml:id",...) has no retained static context

I don't know if it is the same issue as https://saxonica.plan.io/issues/2851 so I had to create a new issue. Sorry if they are the same. Is there any release date for the next version? I've tested the same file with 9.6.0.9 and it works, but I would prefer not to use an older version.
