My bad. I often run stylesheets against themselves for the sake of
convenience when I don't require an input document. I should've
mentioned that in my first post and obviously, it won't work the minute
I change this practice.
To get the base URI of the current stylesheet module (or more
strictly, the base URI of the current expression in the stylesheet),
use the static-base-uri() function. (Different parts of a stylesheet
module can have different base URIs if you use xml:base, or if parts
of the stylesheet are contained in external entities).
I wasn't aware of the existence of that function (odd, considering we
implemented and tested it). But this looks like exactly what I needed.
There's no way to determine the base URI of the "currently executing
main stylesheet" unless you put a global variable in the principal
stylesheet module and bind it to static-base-uri() (and avoid using
xml:base or external entities, and ensure that the API via which the
stylesheet is loaded actually preserves the URI information...)
A lot of buts, but a workaround that could work in trivial
circumstances, thanks.
