But there is no requirement on the value of the "whiteSpace" facet. Can it be "preserve"? It's not possible to get whiteSpace=preserve if the list type comes from a schema document, but what if it's "born-binary"? 24402 1 davep 2009-03-24 21:50:23 +0000 (In reply to comment #0) > But there is no requirement on the value of the "whiteSpace" facet.

In Datatypes, section 2.4.1.2, List Datatypes, we assert: "When a datatype is derived by ·restricting· a ·list· datatype, the following ·constraining facets· apply: ·length· ·maxLength· ·minLength· ·enumeration· ·pattern· ·whiteSpace· ·assertions· For each of ·length·, ·maxLength· and ·minLength·, the length is measured in number of list items. The value of ·whiteSpace· is fixed to the value collapse." That last sentence should settle the matter. Perhaps it should be duplicated in Structures? Note also another aspect of your quote: "2.2.1.2 D.{facets} contains only the whiteSpace facet component." I vaguely recall there was some reason we required that a construction of, say, a two-items-required list of integers datatype would be disallowed and one would be required to first construct an arbitrary-lists-of-integers datatype and then derive (using the length facet) the desired one. Presumably to avoid constructing and deriving-by-facet in the same step. Without looking, I suspect that our current derivation/construction mechanisms, even without that explicit restriction, don't have that capability. 25036 2 sandygao 2009-05-08 16:37:41 +0000 During its 2009-04-17 telecon, the schema WG adopted a proposal to address this issue, by updating clause 2.2.1.3 in "Derivation Valid (Restriction, Simple)" to read: 2.2.1.2 D.{facets} contains only the whiteSpace facet component with {value} = collapse and {fixed} = true. With this change, the WG believes that the issue raised in this bug report is addressed. As the reporter of this bug, I'm closing it accordingly.
