Actually, we don't *want* to change it, because otherwise browsers would not really understand that we are serving them XHTML, and might have all kinds of trouble displaying it. The namespace declaration serves to identify the type of the XML element to which it applies, i.e. just what kind of information is encoded within it. The above namespace declaration identifies the <html> element and all its contents (or at least, all its elements that do not have a *different* namespace declaration) to be XHTML, and browsers know how to render it. Besides, as Ceri says, there's no harm, as nothing should *ever* be accessing the w3.org URL; namespaces are *not* guaranteed to contain URL's with valid content, and they are not even guaranteed to contain valid URL's. A namespace may be any sequence of characters; it is customary to use URL's for easy identification and versioning, but it is just that - a custom. Anyway, don't change it, or people will not be able to see our pages :) G'luck, Peter --=20 Peter Pentchev roam@ringlet.net roam@sbnd.net roam@FreeBSD.org PGP key: http://people.FreeBSD.org/~roam/roam.key.asc Key fingerprint FDBA FD79 C26F 3C51 C95E DF9E ED18 B68D 1619 4553 If wishes were fishes, the antecedent of this conditional would be true. --wYehVJ3WBY9OQfE8 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (FreeBSD) iD8DBQE/MS6Z7Ri2jRYZRVMRAjBzAJ4iaEWiKm1G3vZzNkCMjo0ozsP7pACgwuVJ tuTcYga4pf5y8+3nX78sdT8= =t0+H -----END PGP SIGNATURE----- --wYehVJ3WBY9OQfE8--
