Read full entry » RE: Algorithm for merging the pattern facets in a base simpleType with a subtype?Posted 4/20/2011 5:49:18 AMThanks Michael and Liam. Truly excellent. I think that now I have an algorithm for determining how the pattern facets in a simpleType and in its base type (and its base type's base type and so on) constrain a simpleType. Would you verify my algorithm please? Consider simpleType A that has a base . . .
