Well the issue is how do you constrain where an element can be inserted.

Suppose you have the following snippet 
<ns:Elem1>
  <ns:Elem2>
  </ns:Elem2>
</ns:Elem1>

and you want to insert the <dsig:Signature> element inside this.

In NVDL can you express the constraint that <dsig:Signature> can only be
after </ns:Elem2> and not anywhere else?

Pratik




The answer is:

Yes, with NVDL you can specify precisely where an element must be placed.
For those people who are interested in how this is accomplished, see slides
120-124 in the NVDL tutorial: http://www.xfront.com/nvdl/index.html

Rob
