"2.4 Predicates
An axis is either a forward axis or a reverse axis. An axis that only ever
contains the context node or nodes that are after the context node in
document order is a forward axis. An axis that only ever contains the
context node or nodes that are before the context node in document order
is a reverse axis. Thus, the ancestor, ancestor-or-self, preceding, and
preceding-sibling axes are reverse axes; all other axes are forward axes.
Since the self axis always contains at most one node, it makes no
difference whether it is a forward or reverse axis. The proximity position
of a member of a node-set with respect to an axis is defined to be the
position of the node in the node-set ordered in document order if the axis
is a forward axis and ordered in reverse document order if the axis is a
reverse axis. The first position is 1."

This is the first paragraph of section 2.4 Predicates. It deals
exclusively with axes and its place is in section 2.2 Axes.


Thanks,

Dimitre Novatchev.
