Any XML that is impropertly syntacizated should be rejected. If we are to maintain the purity of XML, such transgressions should never be permitted. Indeed, the offenders of The Standard should punished, if not purged. Any lesser response would encourage the dilution of The Master Protocol.

In fact, there should be a web application that immediately punishes, through, say, electrical shock, any deviations in XML format in a document and, if the non-conforming coder insists on publishing such to the web -- then, well, there is no saving the author and he/she should be abended and the document DES-wiped, before he can do any further damage to the structure of the internet.
