Me too.
When advocating XML in other communities such as VRML, XLink is 
cited as one of the advantages of XML.  Not being part of the 
deliberations, I am uncertain as to what the delays are given 
that the original drafts were promising and on the surface, 
quite clear.  For the work I am doing, an XLink model would 
be useful if for nothing else, the properties, just as the 
RDF Dublin Core has been and XSchema may be.  One benefit 
of suddenly being forced to do everything relationally is 
the insight into some of the designs floating about.  So, please: 
1.  A standard for primitive/core datatypes
2.  XLinks
ASAP,
