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: http://www.w3.org/TR/2001/REC-xmlschema-0-20010502/#any 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. ;-} Bob Foster Razvan MIHAIU wrote: > > Hi, > > > > > I have noticed that the element type ANY from DTDs allows only elements > that have been declared in the DTD while the element type "anyType" from > XML Schema allows any kind of element inside it (even elements that were > not declared inside the Schema). > > I have tested this behavior with XML Spy 2005 and xsv 2.8-1. > > > Isn't this against the spirit of XML Schema (which is supposed to allow > more control, not less) ?
