Hi CSS folks,

Sorry for jumping in late. I just realized that the CSS Compositing and Blending is using the property 'isolation'[1]. I see the problem is that 'isolation' does exactly the same thing as 'enable-background' [2] from Filter Effects. I would rather avoid to implement two properties with the same behavior but different names and keywords:

isolation: isolate | new
enable-background: accumulation | new

Personally I don't have a preference over the property name. But 'enable-background' is already implemented in a lot of SVG viewers as well as Opera and Internet Explorer 10. So there is no way for the Filter Effect spec t change the name (which is based on the RC of SVG 1.1 [3]).

Is it possible that we can use the same property name and keywords in CSS Compositing and Blending and share the definition of the property?

Greetings,
Dirk
