RE: [xsl] Sequences: how to get them (eg in Saxon)?

["Michael Kay" <michael dot h dot kay at ntlworld dot com>]

The only documentation for these features thaht's currently available is the
XPath 2.0 working draft at http://www.w3.org/TR/xpath20

XPath 2.0 changes the type system. Whereas XPath 1.0 allows values of four
types (number, string, boolean, or node-set), in XPath 2.0 the value of
every expression is a sequence of items (a single item is treated as a
sequence of length one). The items in a sequence may be nodes or atomic
values, and the atomic values may be any of the simple types of XML Schema,
for example boolean, string, decimal, double, date, QName, or anyURI.
Node-sets in XPath 1.0 are replaced by node sequences; the difference is
that a node sequence may be in any order, not necessarily document order.
