Hi all, In our inline markup sub-committee meeting today, we touched on several cases where validating some elements may be complicated and possibly not supported by XML Schema 1.0. This is likely something that will affect the rest of the XLIFF elements. So I got the action item to bring this topic to the TC: What is the fallback solution if we cannot validate some complex/conditional constructs with XML Schema 1.0? Custom tool, XML Schema 1.1, RelaxNG and Schematron were mentioned. The SC has no specific recommendation on this, but we are just wondering what are the possible solutions. Cheers, -yves
