Not possible, since the user agent doesn't know anything about the content model of the unknown elements it cannot parse the document. >Except the validator. No, it validates your document against your given/selected document type definition. If you selected HTML 4.01 Strict, it will complain about elements and attributes not defined there. If you want to use proprietary markup, get a proprietary DTD from the entity who defined those proprietary extensions or write your own. >I'd like to be able to check real-world web pages, not just showcases >to compatibility with the HTML specification.
