AW: Proposals for new/amended functions: summary

That’s a helpful summary, thanks.

> Let me know if you think I've omitted or misclassified anything.

The following ones could be added:

• Issue 29: array:values, map:values (array:members and map:entries are already listed)
• Issue 74: parse-html
• Issue 97: init, heel/foot
• Issue 123: duplicate-values

The function name "is-NaN" could be discussed. Other predicate functions in the spec (nilled, empty) don’t start with "is-", various EXPath functions do so, though.
