RE: Re[2]: [cgmo-webcgm] APS 'name' attribute in XCF?

[Dieter Weidenbrück <dieter@itedo.com>]

I think it is worth mentioning (after hours and hours of discussions
regarding this topic), that the XCF is not exported to represent an
XML encoding of some sort of the CGM file, but rather a file that
holds information that does NOT reside inside the CGM, and that
needs to be changed at runtime.
I still believe there are use cases for the other (descriptive) case,
however, the spec has not been written for this as is.

Some other process usually.  However, once WebCGM 2.0 viewers are available,
having this available within the viewer might suffice.  It is very difficult
(for me at least), to predict how users are actually going to use this
stuff.

Yes.

Yes, I got that impression from reading the 2.0 spec.

Right now, my main concern is exporting companion files.  But, I will
eventually have to read them back just like everyone else.

I'm not sure that's still required if you use XML namespaces.

RO> Hi Robert,
