Comments/justifications for changes:
It might be possible to misunderstand the requirements. From the text, as it is written now, the reader might assume that a space element can only have one property core:boundary.
I suggest to simply change "the" by "each" in the second part of the second sentence:
So instead of "If a space element [...], the property SHALL contain [...]." I think it would be better to write "If a space element [...], each property SHALL contain [...]."
Part A to be completed once. Iterate Part B as needed.
