It's pretty obscure territory though, and you may find that not all processors get it right. You can produce a namespace node in the result tree by copying a namespace node either from a source document or the stylesheet. Normally namespace nodes are copied when a source element is copied using <xsl:copy> or when a literal result element in the stylesheet is copied; however one of the errata makes it clear that if there are no conflicts, you can also copy a namespace node using <xsl:copy> or <xsl:copy-of>, which means you can inject a new namespace node into the result by having a secondary source document <dummy xmlns:ppp="some.namespace.uri"/> and doing <xsl:copy-of select="document('dummy.xml')/*/namespace::ppp"/> When a namespace node is present on the result tree, the serializer must output a namespace declaration for it, and it is not allowed to change either the prefix or the URI. This means you can safely use this prefix in the value of a generated attribute. Mike Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
