Hopefully you see the contextual indication of where the
syntax error is, don't you?

It has been two years now since I had plan to write a better parser.
But it's a big task and I never found time yet to start such 
development. I hope I can do that soon.

In fact the information was in the compiler. There was just a typo
in the code that displays the error message. Instead of displaying
the feature names, it was displaying the name of the current class.
This has now been fixed in the version of the compiler in Subversion,
and now you should get:

[VMRC-2] class XM_XSLT_STYLE_ELEMENT (50,2): replicated features 
XM_XPATH_DEBUGGING_ROUTINES.string_equality_tester, 
XM_XPATH_TREE_ELEMENT.uc_string_equality_tester have not been selected.
----
[VMRC-2] class XM_XSLT_INSTRUCTION (37,2): replicated features 
XM_XPATH_DEBUGGING_ROUTINES.string_equality_tester, 
XM_XPATH_COMPUTED_EXPRESSION.uc_string_equality_tester have not been 
selected.

You should probably rename them so that they share the same name
and hence avoid the need for a 'select' clause.
