XML MULTI-Fragment Interchange?

[Don Park]

The first draft of the XML Fragment spec allows only one Fragbody.  Could
someone from the WG shed some light on why this constraint is important?

Multi-fragment packages are useful in many situations such as query result
representation.  Although it is possible to define a packaging mechanism
that handles multiple fragments, a fragment context information (FCI) must
be provided for each fragment because the spec does not allow FCI to be
shared by multiple fragments.

A possible example of a multi-fragment package follows:

<?xml version="1.0"?>
<p:package xmlns:p="http://www.w3.org/XML/Package/1.0"
           xmlns:f="http://www.w3.org/XML/Fragment/1.0"
           xmlns="">
  <f:fcs>
    <transaction>
      <purchase>
        <book/>
        <f:fragbody idref="frag1"

fragbodyref="http://sales.acme.com/trans/19990207-1234#root().child
(1,purchase).child(2,book)"/>
        <f:fragbody idref="frag2"

fragbodyref="http://sales.acme.com/trans/19990207-1234#root().child
(1,purchase).child(5,book)"/>
      </purchase>
    </transaction>
  </p:fcs>

  <p:body id="frag1">
    <book>
      <Author>J. R. R. Tolkien</Author>
