The infoset specification came out after DOM and SAX and XPath, and attempted to unify the various different models. XPath (1.0 in this case, I assume) has its own notion of what is and is not important (or even visible). XSLT (1.0) builds upon XPath. > If it is XPath/XQuery DM identity - then if as you say there may be no idea > of a DocType there, then that is a perhaps a flaw. I dunno if they've addressed the issue in the XQuery Data Model (which is post-infoset, and an attempt to be still more formal and rigorous), as the doctype declaration or internal subset effectively exists at a "different layer" of processing (this is true even for bare XML 1.0, pre-edition-X, pre-namespaces, pre-infoset). It is, roughly speaking, the same reason that an identity transform of é is considered correct if it produces é (the transformation does not operate at the processing level that exposes general parsed character entities; it just gets characters ... and likewise, the doctype decl and internal DTD subset are gone before it has a chance to look at them).

(In the UK, which is seeing a vigorous popular backlash against "fat cat" pay packets, the ratio is 24:1). -- The Register
