How to distinguish b/n a scalar and a node-set having a sing

I am trying to determine whether the value of a parameter is a scalar
or a node-set, and to do so without using extension functions (I
consider node-set() to be "standard", as it will be in XSLT 1.1).

The only problemetic case is:
How to determine whether what seems to be a node-set having a single
text node is actually a node set or whether it is a scalar (the value
of the text node).

Any help would be highly appreciated.

Thanking you in advance,

Dimitre Novatchev.
