Overall this looks good. But I have the following comments:

* Shouldn't the default value for xforms:relevant be true (currently specified value is false)
* How can you validate non relevant nodes? I would expect that non-relevant nodes are considered valid when doing validation on serialisation.
* What is the default value of the xforms:validate serialisation parameter
* Could we rephrase 'When <code>true</code>, nodes marked as invalid in the input sequence are checked (after pruning if pruning is enabled with <code>xforms:relevant</code>). If there is any invalid node, the function raises a dynamic error. No revalidation takes place during this process.'
      *Proposal*: When <code>true</code>, the function raises a dynamic error if there are any nodes marked as invalid in the input sequence (after pruning if pruning is enabled with <code>xforms:relevant</code>). No revalidation takes place during this process.

Kind regards,

All,

As per this action item, I imported the function into XForms. I did so:

- by referring to the external specifications
- and using XSLT and XQuery Serialization 3.0's ability to add
submission methods and parameters to specify behavior which is
specific to XForms.

Here is the diff:

http://www.w3.org/MarkUp/Forms/wiki/index.php?title=XPath_Expressions_Module&diff=3800&oldid=3750

This means some changes compared with the previous text, including:

- the function signatures have changed
- the way to specify parameters (including the serialization method) has changed

I have a few open questions/comments:

- Most standard boolean serialization parameters are "yes" and "no".
Should we use that too, or "true" and "false"? Or accept both?
- There are 2 editorial notes related to linking.
- I chose to raise a dynamic error if JSON serialization fails. It can
fail, right?
- Is it unexpected to users that, by default, non-relevant nodes are
pruned? This is consistent with xforms:submission
- I made xxforms:validate throw a dynamic error. It seems better than
returning a blank string.

Comments welcome.

-Erik
