Perhaps you missed the point. Your embedded system would not store the
XML any more than it now stores the full text distribution with all
comments. You now store a compiled form of the distribution text; in the
future you would store a compiled form of the XML distribution.

I think there are more plusses than minuses in going to XML.
Particularly if an XML or RELAX NG schema is also distributed. It would
probably be necessary to have a converter from XML back to the current
format, but that should not be a problem.
