Re: [xml-dev] Pragmatic namespaces

While I like the Java notation ideas floated around, keep in mind that for many, many developers, the dot notation normally implies child class. For instance:

org.w3.html.body would imply that body is the immediate descendant of org.w3.html, which is the immediate descendant of org.w3, and so forth.

Also, if I'm not mistaken, Microsoft XAML makes use of dot notation XML tag names, but I don't remember off the top of my head whether this was a namespace workaround or a class implication.  I can also foresee potential problems with languages like e4x, which do make use of dot notation in order to perform Javascript get-child operations.

Donkeys can't type very fast... I can see there there might be pushback
for this proposal on the grounds that it's considerably more verbose
than most other current proposals, with the exception of the {...}

See my proposal from yesterday that allowed partial namespaces (http://lists.xml.org/archives/xml-dev/200908/msg00033.html ).

also, it can't easily be made compatible with
things like ch.cern.html (later org.ietf.html, and then org.w3.html,
of course, and also ch.iso.html...)

If you make the namespace more obviously separable from the local name, (for example, by using a : rather than another .), then the XML parser can be informed as a local implementation that namespace org.ietf.html is an alias of namespace org.w3.html (or better still, namespace html.ietf.org is an alias of namespace html.w3.org).  So when the parser encounters <body:html.ietf.org> it can return the equivalent of <body:html.w3.org>.
