[xsl] XSLT 2 processing of W3C Schema expressed default attributes

["G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx>]

Hi folks!

My expectations of the instance and document model below are that a 
schema-aware XSLT 2 processor will "see" the default attribute expressed in 
the W3C Schema expression and this attribute will show up in a copy-of for 
the entire document.  I'm expecting the output <entry1> will have 
defattr="hello" included since I didn't specify such an attribute in the input.

The output running Saxon 7.6.5 doesn't show the default attribute and the 
documentation at http://saxon.sourceforge.net/saxon7.6.5/index.html doesn't 
discuss the PSVI, so I'm assuming I've messed up somewhere in the 
specification of the schema model ... but cannot see it in this simple 
example.

Can someone point me to where my mistake is and to which collection of XSLT 
2 processors I can work with to see these default attributes?

Thanks for your help!
