I see no reason to uncompress to XML.  Presumably the parse tree that 
one gets from XML
can be stored in a compressed form on disk and recreated  in memory, 
without re-parsing.
I assume that is what Lisp FASL does:  builds up the appropriate symbol 
table and specifies
the creation of links, and a simple assembler.

The only time one would need to use XML is when dealing with a program 
that only knows
XML as text string, or perhaps when dealing with a human programmer, for 
whom XML was designed
as some kind of  external interchange format.
