It does. But... (see below)

In our version of Phoenix (pre 4.0) it was not returning null, but the
empty string.

As far as I see it, now it is not possible anymore to distinguish
between "empty element" (returns "") and "element not present" (returns
null). Many of our applications use these tests.

Or do you mean that putting xml:space="preserve" at the root element, we
will continue to be able to use these tests without any side-effects?

The key question is: can we get the v1.15 behavior back by putting
xml:space="preserve" at the root node?

Sorry if I sound confused, I'm just trying to determine, what the exact
consequences are for our applications :)
