According to the syntax in "XML Path Language (XPath) Version 1.0"
(http://www.w3.org/TR/xpath),
a <Step> is either the sequence <AxisSpecifier> <NodeTest> <Predicate>* OR an
<AbbreviatedStep>. The latter may expand to a '.', therefore, no
predicate after '.'
With self:: node() [A] you follow the first alternative of the <Step> NT.

Hi Folks,
Why is this XPath 1.0 expression illegal:
.[A]
whereas this XPath 1.0 expression is legal:
self::node()[A]
Isn't '.' a shorthand for 'self::node()'? Shouldn't I be able to interchange
the two in any expression?
