Hi Chris

Thanks for the feedback. I'm happy with the responses and that SVG Print
and Color Management have been separated. This gives the color aspects
more weight. I'll continue to follow the developments here and I hope
I'll have time at some point to do some implementation work to verify
the spec. No promises. ;-)

SVG Print has been split into two specifications, one for the multipage functionality and one for color management. It is in connection with the latter of these that I am contacting you now.

Given the different constraints on syntax for each spec, such alignment is likely to be at the functional rather than the syntactic level, but that is the level which most affects implementations in terms of shared code and concepts anyway.

It is therefore likely that the XSL+SVG combination would also start seeing SVG which uses calibrated CMYK.

In other words the relevant tools are likely to start producing these profiles, and there are likely to be named color profiles available that people can pick up and use.

This part is not fully specc'ed out yet, but there is an early editors draft of SVG color at
