XSLT processor used by DT2 ?

Is DT2 internally using an XSLT processor for any of its imports etc ?

If so, could that be exposed through applescript, or found in some other way by user scripts ?

(I would like to use XSLT for a custom import function, and would prefer to save users the trouble of downloading and installing an XSLT processor from elsewhere - as far as I can see the default OS X installation doesn’t seem to include anything like Saxon).

DEVONthink doesn’t use XSLT.
