Sounds like alt text, what if this is very different to the actual
text? Risk of it being outdated when the CGM is revised. what does
'badly structured' mean here? "

Unlike alt text, WebCGM user agents do not display the content of
'content' if the graphical primitives cannot be displayed. It's
only purpose is to facilitate documentation/searching operations.

As for the 'very different to the actual text' question, would could
add some guidelines similar to the HTML alt text guidelines:
http://www.w3.org/TR/html4/struct/objects.html#alternate-text
And definitely put an emphasis on the fact that authors should update
the 'content' attribute if the graphical primitives of the APS are
modified. 

As for 'badly structured', simply provide an example.
