Hello all, I'm trying to validate a small SMIL file that has some customTest elements which are referred by a customTest attribute. Validation is done by using the DTD W3C provided and by an XML validator tool (XMLSpy). According to the W3C Spec (Content Control Module 4.3.2): "The syntax of the customTest [attribute] is defined as list of customTest element identifier references, separated by the '+' character" But the DTD defines the customTest attribute as an IDREF (smil-attribs-1.mod). As such, the DTD allows only one (and exactly one) element identifier reference. Thus validating a SMIL document that contains multiple customTests references in one single customTest attribute fails! --e.g. (reduced example)-- <smil> <head> <customAttributes> <customTest id="testA" title="Test A" defaultState="true"/> <customTest id="testB" title="Test B" defaultState="true"/> </customAttributes> </head> <body> <par> <video src="movie" customTest="testA + testB"/> </par> </body> </smil> If in the example above the customTest attribute is replace with customTest="testA" this SMIL document will validate, but we want to express that "movie" is available only if testA AND testB are true. -- Have I overlooked something? Can I circumvent the problem somehow? Is the DTD that W3C provider incorrect? And if so, does anybody have a suggestion how to change it such that it resembles the specification? Any feedback is appreciated!
