In XSL WG discussions of issue qt-2004Feb0625-01 (see [1]) a separate problem emerged: it is not safe to preserve the type annotation of an attribute when the attribute is copied (using xsl:copy or xsl:copy-of), because there is no guarantee that the namespace context of the new attribute will be the same. This affects the outcome if the attribute value is an xs:QName. This also raises questions about the precise meaning of xsl:copy[-of] when applied to QName-valued attributes - does it copy the typed value or the string value? In the first case, the namespace prefix of the QName value is lost, in the second case, the namespace URI is lost. There are similar discussions affecting the semantics of attribute copying in XQuery, so this is a joint issue.
