How does RELAX NG provide a mechanism for specifying operations on these datatypes? It would be easy enough to specify the lexical form of longitudes and latitudes then place them in a publically accessible XSD file but it would be useless since there would be no language for specifying value space relationships in the schema. For instance how would one specify what the semantics of maxInclusive, minExclusive, maxExclusive, minInclusive, etc should be? If RELAX NG can do this I'd love to see a sample RELAX NG file that does this. Can you provide one? From what I've seen RELAX NG supports datatype libraries and parameters to these data types but this seems to imply that each RELAX NG validator needs to know how to deal with type libraries so it isn't simply a case of writing a schema but instead actually altering the code for a RELAX NG validator for it to support a datatype library. So interoperability goes to hell unless one can convince every RELAX NG validator to support your homegrown datatypes. If I am mistaken I'd appreciate clarification. -----Original Message----- From: J. David Eisenberg [mailto:catcode@c...] Sent: Sun 8/4/2002 10:14 AM To: Simon St.Laurent Cc: xml-dev@l... Subject: Re: maps . Or, in another rational perspective, use Relax NG, which lets you implement your own data type libraries, which can be shared through the magic of open source. -- J.
