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. ht -- Henry S.
