Re: Getting the data type of an element

> How can a sequence of anything be an instance of xs:boolean Mike?

Just as Xpath 1 doesn't have a "node" type, only a "node set" type,
Xpath 2 does not distinguish between a sequence of one item and a single
item. Basically _everything_ in Xpath 2 is a sequence.

> What's the difference between . and data(.) please?

. is the current item (most likely an element node in this case)
data(.) is the typed value of that node.
so if you are on an element node
. instance of xs:boolean
will be false as . is an element not a value, and in particular not a boolean.
but
data(.) instance of xs:boolean
will be true if the content of the element is schema typed to be
boolean.
