[relaxng-user] Re: RELAX NG book, very cheap

[John Fuller]

As much as I admire the elegance of RELAX NG, to implement web 
services, it's pretty hard to get around using at least the XML Schema 
Part 2 Datatypes.  From SOAP attributes themselves to the informative 
schemata people provide in their web service specifications, it seems 
like at least those types are pretty widespread...
I 've found myself for the sake of expedience using xsd a lot more than 
I wanted...

Of course, I know there's a mapping, and mapping tools,
and no need to use the schema language, but there seem to be a lot of 
xml schema tools
particularly related to wsdl and code generation.
