David C.'s being a little pedantic (now there's a surprise) and saying
that the *node test* "node()" matches attribute nodes. He's not saying
that the *pattern* "node()" matches attribute nodes.

The *pattern* "node()" as in:

<xsl:template match="node()">
  ...
</xsl:template>

is actually a shorthand for the pattern "child::node()", and matches
any node that is a child of another node. Attributes aren't children
of any other nodes, so they don't match this pattern.

However, if you use the pattern "attribute::node()" (or @node()) then
that will match any node that is an attribute of another node, and
will therefore match attributes. This is because the node test
"node()" matches all nodes, including attributes.

The same goes for expressions: the expression "node()" is a shorthand
for the expression "child::node()" and will select all child nodes of
the context node. The expression "attribute::node()" or "@node()" will
select all attributes of the context node; since only attributes are
attributes of a node, it's equivalent to do "@*", which has the
benefit of being shorter, so that's what we use most of the time.

Cheers,

Jeni
