Section 8.4.3

In Schema-less mode, when using the SE(*) production, should the creation of the SE(qname) production be done before the evaluation of the element content?



In most case, this has no impact. In case of recursive elements, this leads to better compaction.

Moreover, in case or recursive elements, the current specification seems to imply creating several SE(qname) productions.

WG Notes: mistake in the spec, will be corrected

Resolution: Yes, you make a very good point. Thank you for catching this. The next version of the specification will be updated to add the SE(qname) production before evaluating the element content.
