[PHP-DEV] annoying DOM limitation

[George Schlossnagle]

While hacking on a PHPDoc -> WSDL generator, I ran into an annoying  
limitation in the dom extension: you can't add a namespace to a dom  
document unless you have an element in that namespace.  Why might you  
want to do this?  Well, a common thing is to have your xml-schema  
types to be specified as attribute values, i.e.

<element name="foo" type="xsd:string"/>
for this to work I need xsd to be an alias for http://www.w3.org/2001/ 
XMLSchema.

To work around this, I added a DomElement::addNS($uri, $alias) method  
to Dom.  Adding the namespace 'manually' as an attribute on an  
element does not work.

I know this isn't part of the Dom spec, but it's incredibly useful.   
Does anyone (Rob, Chegru) mind me adding it to HEAD?
