Document Type Definitions are probably going to be replaced by XML Schemas one day....? You might want to check them out too! =] DTDs can specify valid tags, order of tags, format of tags, content of tags / correct type, mandatory fields etc. I think they can pretty much cover everything! -----Original Message----- From: Alexander G.

Not really, just adds something new. I'd probably have to learn about document type definitions (or whatever it is called) and see how they define the fields inside structures. Do they just give a list of tags or do they specify what kind of values the tags have too? - Alex This transmission is confidential and intended solely for the person or organisation to whom it is addressed.
