11.3 Using Values of Variables and Parameters with

< copy-of
   select= expression >
   <-- Content: -->
< /copy-of>

The xsl:copy-of element can be used to insert a result tree fragment into the result tree, without first converting it to a string as xsl:value-of does (see [Generating Text with ]). The required select attribute contains an Expression. When the result of evaluating the expression is a result tree fragment, the complete fragment is copied into the result tree. When the result is a node-set, all the nodes in the set are copied in document order into the result tree; copying an element node copies the attribute nodes, namespace nodes and children of the element node as well as the element node itself; a root node is copied by copying its children. When the result is neither a node-set nor a result tree fragment, the result is converted to a string and then inserted into the result tree, as with xsl:value-of.
