SVG switch element

Project:EPUB Maintenance
Component:Open Publication Structure (OPS)
Category:bug report
Priority:normal
Assigned:PSorotokin
Status:completed @ 2.0.1

SVG has its own switch element similar to OPS switch. It works by looking at requiredFeatures attribute which list URLs identifying features that are needed to process a particular switch clause. I think we need to clarify what feature URL corresponds to its usage in OPS context. I think it is natural that feature with URL "http://www.idpf.org/2007/ops" would imply that OPS is supported. It would be nice to state it explicitly.

Description
Issue Id: 
24
Resolution: 

Errata: add the following text to the OPS spec section "2.5.1: General Notes on SVG Usage":

Since OPS is by definition supported in conforming Reading Systems, requiredExtension attribute on SVG elements with the value "http://www.idpf.org/2007/ops" MUST always evaluate to true. See SVG 1.1 Recommendation section "5.8.4 The requiredExtensions attribute" for more information on requiredExtension attribute processing.

Agree with your proposal Peter, it makes a lot of sense to correctly identify OPS in a SVG switch.

I propose we move it to errata and add the following text to the OPS spec section "2.5.1: General Notes on SVG Usage":

Since OPS is by definition supported in conforming Reading Systems, requiredExtension attribute on SVG elements with the value "http://www.idpf.org/2007/ops" MUST always evaluate to true. See SVG 1.1 Recommendation section "5.8.4 The requiredExtensions attribute" for more information on requiredExtension attribute processing.
