That works for atomic values (with the exception of NaN) but not for nodes (my mistake in my last post!). Using XQuery notation:Is it fair to say deep-equal could mean:deep-equal(A, B) means (count(A) eq count(B) and every $i in 1 to count(A) satisfies A[$i] eq B[$i]). Therefore deep-equal((), ()) is true.
every $i in 1 to max((count(A), count(B))) satisfies A[$i] eq B[$i]
which would then return false, as its only the length check that is causing it to return true (and thats only there to avoid also checking every item in B is equal to A)
<a>3</a> eq <b>3</b> is true
deep-equal(<a>3</a>, <b>3</b>) is false
