Competition and standards
It should noted, that W3C XHTML validator have some limitations, so there must be another way to check documents for conformance with XHTML and XML specifications.
Quote from O'Reily:
XML documents do not have to have an XML declaration. However, if an XML document does have an XML declaration, then that declaration must be the first thing in the document. It must not be preceded by any comments, whitespace, processing instructions, and so forth. The reason is that an XML parser uses the first five characters (<?xml) to make some reasonable guesses about the encoding, such as whether the document uses a single byte or multibyte character set. The only thing that may precede the XML declaration is an invisible Unicode byte-order mark.
This is wrong for W3C validatator.
