To improve build time testing (e.g. done in the (nearly finished) Debian package) it would be nice if the following features would be implemented:
top level Makefile aware of (some of) the tests/Makefile targets.
shipping of the reference files in the pasdoc package.
ensure non-zero return value if results are not as expected. Currently the tests pass, even when pasdoc, xmllint and onsgmls are not on the path or installed.
