actual_cast()

["Jason E. Stewart" <ja...@openinformatics.com>]

Hey All,

After working with Xerces.pm for a little while, I noticed how
actual_cast() is needed to rebless DOM_Node instances into the proper
subclass. It's great that the function exists, and I wanted it to
always be applied. 

So I've modified postModule.pl so that every function that returns a
DOM_Node calls actual_cast() before it's returned.

The only problem is that I'm not clear on what this might break. Are
there any cases in which we *don't* want to down-cast automatically? 

jas.

I can't think of any.  By inheritance from DOM_Node, there should be no 
loss of API. :-)
