At the moment, LinearDoc.js will accept ill-formed XML containing syntax like <!--- foo ----> , which then gets misinterpreted.

For example, the document '<p>foo<!-- bar -->baz</p>' correctly gives the following LinearDoc (XML dump):

  <p>
  <cxtextblock>
    <cxtextchunk>foo</cxtextchunk>
    <cxtextchunk>baz</cxtextchunk>
  </cxtextblock>
  </p>

However, the ill-formed document '<p>foo<!--- bar ---->baz</p>' gives the following LinearDoc (XML dump):

  <p>

The expected behaviour is to signal an XML parser error on reading the ill-formed document.

This bug occurs because the nodejs sax 0.6.0 module silently accepts ill-formed XML, which violates 5.1 of http://www.w3.org/TR/REC-xml/ ("Validating and non-validating processors alike must report violations of this specification's well-formedness constraints").
