I'm not sure I understand.  I got them via the list, and both the .cgm and 
the .htm attachments were intact.

On the other hand, if you look at the message in the Kavi archive,
http://lists.oasis-open.org/archives/cgmo-webcgm/200709/msg00087.html ,
then you will notice that Kavi seems to have put the HTML in-line and 
dropped the attachment.

All hail to Kavi !!!  (What a piece of junk.)

That's a good topic for discussion (telecon).  A couple of practical 
(short-term) ideas come to mind:

1.) our proposed examples page could have one-jump links to every vendor's 
viewer that works on the examples; and these should be trivial to download, 
install, and run.

2.) maybe we could make a "cartoon strip" composite that shows what one 
will see with an enabled viewer?

Explain?  What does it mean to "change the style property within the 
APS"?  You can change a Style Property through DOM for a whole APS, or 
through XCF for a whole APS.  But "within the APS", you can only change CGM 
primitive attributes (or ApsAttrs in the APS header).

I don't think feature creep is a big problem at this stage.  The entire 
collection of endorsed 2.1 extensions is pretty small at this point.  On 
the other hand, here is an item that proves useful to people actually 
writing WebCGM applications.
