 In the 2nd Last Call of the XSLT 3.0 specification, section 5.6.3
"The Meaning of a Pattern":

       http://www.w3.org/TR/2014/WD-xslt-30-20141002/#pattern-semantics

contains this text:


"The meaning of the pattern is then defined in terms of the semantics
of the equivalent expression, denoted below as EE.

Specifically, an item N matches a pattern P if the following applies,
where EE is the equivalent expression to P:

1. N is a node, and the result of evaluating the expression
root(.)//(EE) with a singleton focus based on N is a sequence that
includes the node N

If a pattern appears in an attribute of an element that is processed
with XSLT 1.0 behavior (see 3.10 Backwards Compatible Processing),
then the semantics of the pattern are defined on the basis that the
equivalent XPath expression is evaluated with XPath 1.0 compatibility
mode set to true."

Then there follows an example, a paragraph with explanations, and a
note. This ends the section.

It seems that an intended second case (2) for the case when N is not a
node, is omitted.

I would appreciate this to be confirmed or if this isn't so, to have
an explanation why a list of one case was included and where in the
spec to find the explanation of the meaning of the second, omitted
case.
