Re: Can i specify a rectangle within an image tag in a svg file

The 'correct' behaviour of an implementation for such incorrect nested
elements is described in C.2:

'Within an SVG document fragment, any subtree that is rooted by an unknown 
element (including those in the SVG or XML Events namespaces) or a known 
element that occurs in unexpected location, is not rendered. '

This might be useful to test correct behaviour of implementations for faulty
documents, but is in general not intended to force authors to write incorrect
documents ;o)
