[xml] XML Schema is confusing

["Mark Kotyk" <mkotyk navtechinc com>]

I'm currently working on a project that reads an XML Schema and generates C code
to read and write a document of that type (sort of like CORBA IDL's).  At first,
I was going to go with full blown document validation, but decided that it would
be better handled by the xml parsing lib. 

In my exploration, I discovered that XML Schema has a schema of its own, written
in (of course) XML Schema.  This recursive definition trickles down quite a
ways, to where it defines the types of facets a "simpleType" may have.

The question I pose is this:  Is it better to write some sort of bootstrap
Schema validator/compiler(??) that in turn reads the W3C "XML Schema" schema and
validates the document from there, or just hardcode the whole schema validator.

Future flexibility vs complexity?
