There is one example in which there are some typos--thank you for
pointing them out.  The rest of this message expands on things a bit.

The XML Fragment Interchange specification normatively describes
the syntax and semantics of the fragment context specification
in sections 1-6 (formally defined in section 5).  

All *packaging* information and examples are in the non-normative
appendices (B and C), and--as stated therein--are only non-normative
suggestions for a possible packaging mechanism.  An official
packaging mechanism awaits development by the XML Packaging WG
which is chartered but not yet constituted.

Note that "fragbody" (shown as <f:fragbody> in the examples) is
in the fragment interchange namespace defined in section 5, not 
the "packaging" namespace suggested in appendix B to which p:package
and p:body belong.

The outline of a possible package shown in appendix B should help
make clear (at least in an informal way) the roles of p:package,
p:body, f:fcs, and f:fragbody.

There is one place in the example in appendix section C.1 where
the wrong namespace prefix is used several times.  The example
at the end of C.1 currently reads (except for some elisions):

  <?xml version="1.0"?>
  <p:package xmlns:p="http://acme.com/Packaging/1.0">
    <p:fcs xmlns:f="http://www.w3.org/XML/Fragment/1.0"
          sourcelocn="...">
      <transaction>
        <purchase>
          <book/>
          <p:fragbody/>
        </purchase>
      </transaction>
    </p:fcs>

    <p:body>
      <book>
        . . .
      </book>
    </p:body>
  </p:package>

Instead, the namespace prefix of "f" (rather than "p") should
be used for the <f:fcs>, <f:fragbody>, and </f:fcs> tags.  I
apologize for the confusion these typos may have caused.
