Hello.

By priority.

1. saxon:preview should be in the core. This 
roadsign will solve memory problems for wide 
range of applications. 

2. saxon:evaluate should be in the core. This will 
allow writing better ( and more efficient ) code 
than namespace-alias trick, still being 
access by value and in fact being better for 
compilation than namespace-alias trick.

3. key() should go away, but xsl:key should become a 
universal roadsign.

4. document() should accept only URI. 

Rgds.Paul.
