In xslt 1.0, RFTs cannot be used in place of nodesets, so you cannot operate on the output. Some processors have an extension that does let you use them as if they were regular nodesets. When you declare a variable the way you did, the processor creates a RTF and assigns it to the variable. That is why you got the error message. But you could simplify you variable and get the result you expected - <xsl:variable name="vchapmod1" select="document(concat(string($vchapmod/attribute::docref),'.xml'))"/> In this construction, you select a nodeset and assign it to the variable, so you will be able to use it.
