Re: [xml-dev] Serialization of XDM - Use cases / Proposal

[Kurt Cagle <kurt.cagle@gmail.com>]

I'm going to ask what may be an obvious question, but wouldn't it make sense for a serialization of a sequence to correspond on the output to the serialization on the input? That is to say, if you had a structure:

("foo",5,<bar><bat/></bar>,<!-- foo -->)

internally, wouldn't that also be the serialization format? Admittedly, there's a little more complexity in dealing with fragments and the like, but at least with the sequence case, the delimiters would presumably be those used for XQuery on input.

I also think there is merit in something like the following:

<xdm:typed-document>
  <xdm:type>
     <rdf:bag>
         <xs:string/>
         <xs:unsignedShort length="4" />
     </rdf:bag>
  </xdm:type>
  <xdm:data>
     <address>
       <city>Sydney</city>
       <postcode>2009</city>
     </address>
  </xdm:data>
</xdm:typed-document>

Where the original document can be reconstructed merely by taking the
/*/*[2]/* branch, and there is one element in the type branch for every
element in the data branch.
