[dsdl-discuss] Re: Revised version of DSDL Part 8

I would prefer if DSDL schemas used
 
 "|" and "," rather than "&", to make the translation to DTDs and XSDs
obvious,
 "mixed" rather than "{text & ... }*" to make the translation to XSD obvious

So

any-content = ( mixed {any-element*} )
any-attribute = attribute * {text} *
any-element = element * { any-attribute, any-content }
 

But Eric I don't understand one thing: how do those productions allow
multiple attributes?
It looks like "any-attribute" allows 1 single attribute of any name,
which is not what the intention is.

Cheers
Rick
