     This specifies the *size* of a pointer and its ``<abi>`` and
     ``<pref>``\erred alignments for address space ``n``. ``<pref>`` is optional
     and defaults to ``<abi>``. The fourth parameter ``<idx>`` is the size of the
     index that used for address calculation, which must be less than or equal
     to the pointer size. If not
     specified, the default index size is equal to the pointer size. All sizes
-    are in bits. The address space, ``n``, is optional, and if not specified,
-    denotes the default address space 0. The value of ``n`` must be

The implementation currently allows this but I don't think we need to specify it either way. Most other datalayout properties can be defined multiple times with "last one wins" semantics.
