   Re: [xml-dev] DTD element type "ANY" vs. XML Schema element type"anyType

[ Lists Home | Date Index | Thread Index ]

People can be confused by almost anything. The author you quote is as 
likely to be confused about DTD ANY as about XML Schema anyType.

Just because the anyType element content is unconstrained by the schema 
doesn't mean it won't be further constrained by schemas for other 
namespaces. In this regard, see the any and anyAttribute elements:


As an aside, to argue that something should have been left out of XML 
Schema because it is too confusing is like saying that the Bay of Fundy 
should be left out of the Atlantic because it is too wet. ;-}
