Re: quick XPath question: finding /a/b/c with a default namespace

No, that paragraph describes the interpretation of the QNames in the
XPath: it has no bearing on the interpretation of names in the document.
so in the XPath /a/b/c  refers to elements in the null namespace (or,
more properly, elements in no namespace).

Nope you can not do that as there is no *: construct to wildcard over
namespaces.

If you really don't want to declare a namespace then

/*[local-name(.)='a']/*[local-name(.)='b']/*[local-name(.)='c']
will get you there.

No, it just means that any API for qurying into namespace aware documents
with XPath had better offer a mechanism for setting up the current
namespace/prefix bindings.
