xtm-unknown-elements

Type(s): Issue

Description
- Unknown elements are ignored in order to ensure forwards compatibility, but this means DTD compliance cannot be required. Which is more important?
Opinion
- probably dtd compliance. software etc and perceived reliability of tm is preserved as people will at least only be importing valid xml instances of xtm. The engines can throw back invalid xml errors rather than topic map exception. - Scope: Graham Moore
Resolution
- We don't ignore unknown elements.
