Re[2]: [cgmo-webcgm] Issue CL-d6: 2.3.4 content attribute

[Benoit Bezaire <benoit@itedo.com>]

Hi Lofton,

I wasn't aware that answering a last call comment meant that the comment became normative wording for  the specification ;-)

Feel free to replace: 

Its only purpose is to facilitate documentation/searching operations.

with:

I know you guys wanted to be open about the 'content' attribute in WebCGM 1.0. But you can't have an attribute or a feature in a specification that has no definition. It needs to be somewhat specified.

"Issue CL-d6: [[[2.3.4 WebCGM defined group properties content - an

instances.]]]

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Risk of it being outdated when the CGM is revised.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 I said about CL-d5, I believe we should be careful about saying too much on para, subpara, and content until we know exactly what future requirements these might need to serve.  From my CL-d5 reply...

[[[ 

Finally, we don't need to say more unless pressed further. But we need to keep in mind that we purposely underspecified these things in 1.0, to reserve our options for future standardization (search, flow text, etc). We thought that would happen in a 2.0, but put it aside again (remember flow-text at Cologne?) in order to expedite completion of DOM/XCF -- the highest priority requirements.

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