Is it clear what string the pattern facet of a union type applies to?
Seems to me it should be the lexical space value of the winning type
in the union, i.e. when processing an item with a union type, we go
directly to the member type definitions, and for each one in turn:
1) normalize per the whiteSpace facet _of that member type defn_;
2) check the pattern facet of the union type itself;
3) check the pattern facet of the member type defn;
4) convert to value and check other facets from the member type defn.
If any of (2), (3) or (4) fail, go on to the next member type defn.
I don't think the REC as it currently stands makes clear that this is
what happens, or that it doesn't, but I'm tired and could be missing
something.
