xs:IDREFS

Facets

xs:enumeration, xs:length, xs:maxLength, xs:minLength, xs:whiteSpace

The xs:ID type provides compatibility with the IDREFS attribute type from XML 1.0 DTDs. Like that IDREFS type, the contents of the xs:IDREFS type must be a whitespace-separated list of values, each of which starts with a letter and contains letters, digits, underscores, or colons, and each of which must match an xs:ID value elsewhere in the document.
