To store an external XML doc in a variable am I right in saying I should
use document-node() ?
yes
So what advantage does document-node() give me over element(), node(), or
item()??
item() includes atomic types such as integers so 1 (an integer) and "1"
(a string) are both of type item() but not of type node()
In XPath 1 <xsl:value-of select="node()"/> would return the value of the
text nodes - presumably the node() you are referring to is a completely
different data type and unrelated?

XPath2 doesn't have node sets (They are the XPath1 datatype) it has
sequences. The nearest type to a node set is a sequence of nodes which
is node()*. If you need to store a sequence of nodes you can use node()*
but if your "nodeset" is just a single top level element then you can
use more specific types such as node() or element().

item() includes atomic types such as integers so 1 (an integer) and "1"
(a string) are both of type item() but not of type node() the type
item()*
is a sequence of items and is the most general type, all XPath2 values
match that type.
