Hi Tim

You are correct that the progressive rendering requirements will allow an  
implementation that only renders once, when the entire document is ready.  
This is reasonable, for example, in the case of printing SVG. The point of  
requiring an implementation is to enforce the rules about partial  
rendering - what it is or is not appropriate to render before the entire  
document is assembled.

A paragraph break will be inserted to increase the emphasis on these  
requirements, just before the text

"The following rules apply to progressive rendering: " in the 5th  
paragraph of this section.

Please let us know within two weeks if this response does not satisfy you

for the SVG WG,
