You can write
/example:a/@version-id = 0.4
or
/example:a/@version-id = '0.4'
depending on which you mean [*], in both cases using the API of the
processor to ensure that prefix "example" is bound to namespace URI
"http://www.example.com".
Writing it in a way that doesn't depend on any namespace bindings set up
via the API is much harder - XPath is designed on the assumption that
the bindings will be set up externally, and you're going against the
grain if you don't want to do that.

[*] the first will also match version-id="0.40", the second won't. Yes,
XPath is not a language designed for people who find such fine
distinctions irritating - the "do what I meant, not what I said" brigade.
