The xsl:copy-of element copies of the value of the
            expression in the mandatory select attribute to the result tree
         
If this expression is a string, a number, or a boolean, the effect is the same as using
            xsl:sequence.
         
There is an optional attribute copy-namespaces whose value is "yes" or "no". The default
            is "yes". This controls whether the in-scope namespaces of any element nodes copied by this instruction
            are automatically copied to the result tree. If the value is "no", then namespaces will only be copied
            if they are actually used in the names of elements or attributes. This allows you, for example, to
            copy the contents of a SOAP message without copying the namespaces declared in its envelope.
