[basex-talk] Problem with xi:include - What is the correct href path?

Wed Jun 10 10:40:21 CEST 2015

Hi Kristian,

I see the following alternatives (maybe there are more):

* If we continue to rely on Java's Xerces parser, which is the current
default parser in BaseX (see e.g. [1]). Obviously, we have no control
over the development, and I don't know much about its current status
quo. Maybe things improve with Java 9 [2]? Maybe you find some better
references on the web?

* We could also embed XInclude/XPointer support in our internal XML
parser (which is activated via the INTPARSE option). In this case, we
would have full control, but we would probably only do it as a
"sponsored feature" (financially backed by a customer).

Best,
Christian
