Obviously it can't. If a parser wants to fully validate an XML document it has to read the entire DTD. One of the things it must validate, if the document has RMD=IGNORE, is that the DTD could be ignored without changing the data the application received. A parser that is not validating, on the other hand, can choose to take advantage of the RMD decl and not parse the DTD. Provided that the document has been validated, the non-validating parser will be guaranteed to get the same results as the validating parser.
