5.3 Boundary-space Declaration "The xmlspace declaration" s/xmlspace/boundary-space/ "is not specified formally as the Formal Semantics is defined on the Core language" No, *inference rules* are defined on the Core language. The Formal Semantics (which includes normalization!) *is* defined on the full XQuery syntax. So one could imagine normalization rules that deal with preserving or stripping boundary space. "the Core language, which is an abstract, not concrete, syntax What do you think is *not* concrete about the Core syntax? It's not as featureful as the full language, but I'd say it's just as concrete. "and is typically the result of parsing phase" Huh? The Core syntax is the result of parsing? That certainly doesn't agree with the processing model.
Just sticked to "The semantics of a boundary-space declaration is not specified formally". Thanks for pointing out the various problems in that paragraph. - Jerome
