  I think it is an abuse of XML... nothing is actually marked up. 

  Everything seems to be given as attributes, i.e.:

<field name="verhlen" pos="15" show="45" showname="Version and header Length" size="1" value="45">

  rather than:

<field name="verhlen" pos="15" show="45" showname="Version and header Length" size="1">0x45</field>

  
  It does use the container mechanism to do sub-structure, but I'm not
convinced that I like it this.

  It is worth looking at.
  How widespread is PDML?
