John,

If you aren't going to use the &HeavyData; entity in the file, then
there isn't much point to including the declaration.

You might also check out a few articles on XML.com like:
http://www.xml.com/pub/a/2001/01/31/qanda.html

The above link is to article which includes discussion on using ENTITY,
NOTATION and NDATA to include a GIF in an XML file.

Chris
