Hi Dave,

why not just let the XSP processor create the DOM nodes - and use the
<xsp:logic/> and <xsp:expr/> tags to embed functionality in the output.
If you need to control the addition of elements to the DOM in your own code,
then use the <xsp:element/>, <xsp:attribute/> and <xsp:content/> tags -
they'll be properly resolved, less coding and fewer errors as a result (and
C2 SAX-based compatibility for free!).

eg.

<xsp:page language="java"
  xmlns:xsp="http://www.apache.org/1999/XSP/Core">

  <page>
    <xsp:content>Hello World!</xsp:content>

    <my-new-element>Some more text</my-new-element>
   </page>
</xsp:page>
