I disagree with the proposal for the following reasons:

1) Not all core/module elements should always be preserved when manipulating the document. We need to define this per elements in some cases. Re-segmentation is an obvious example.

2) I assume "XLIFF-defined" means the element is part of a namespace defined by the XLIFF TC. But I don't think this is the same as being a "module". If, for example, part of ITS becomes a module, it's not "XLIFF-defined", but it's still a module.

3) The processing requirements about <target> belongs to the section that defines <target>

So, instead I propose this as general PRs:

-----------

- All user agents MUST follow the processing requirements associated with the core elements and attributes of XLIFF. Those processing requirements are defined throughout the specification.

- A user agent that does not support a given non-core element or attribute SHOULD preserve it, except when a core processing requirement specifies otherwise. (See, for example, section 2.8.3 Segmentation Modification).

-----------

I'm also going to post an email with a initial proposal for the PRs associated with re-segmentation.
