Re: [xml-dev] How can the content of a leaf element be multiple text nod

["G. Ken Holman" <gkholman@CraneSoftwrights.com>]

Had you run:

  string-length(/Test)

... on:

  <Test>abc&amp;def</Test>

... you would have received a value of 7. That would have confirmed 
the internal representation of the characters is not marked up.

I hope this is helpful.
