9.2.7 mixing namespaces

The start-angle and end-angle paragraphs have a schema snippet and a 
describing text, which differ.
When describing the start-angle and the end-angle attributes of the 
draw:circle element, the text uses the svg namespace, e.g. 
svg:start-angle, svg:end-angle, but the actual namespace in the relax-ng 
schema snippet is draw:start-angle and draw:end-angle.
