23.1 Foreign namespaces and private data

SVG allows inclusion of elements from foreign namespaces  anywhere with 
the SVG content. In general, the SVG user agent  will include the 
unknown elements in the DOM but will otherwise  ignore unknown elements. 
(The notable exception is described under Embedding Foreign Object  Types.)

Additionally, SVG allows inclusion of attributes from  foreign 
namespaces on any SVG element. The SVG user agent will  include unknown 
attributes in the DOM but with otherwise ignore  unknown attributes.

It is however imho true of all well-designed XML languages. The reasons 
for forbidding nodes from foreign namespaces are overall rare and local.

Yes. We have been considering using NRL to help with that.
