In fact, from that page, I can see that there is a GPL version, but that the Saxon version is in fact issued on a BSD style licence, and is thus okay. Depending upon which version of Aelfred we have in CVS, this licence issue might be a red-herring.
Saxon itself is the culprit, being MPL 1.0 which is considered "incompatible" with the ASL. And Michael Kay isn't capable on his own to change the license since Saxon bears copyright from both Mike and his former employer ICL, which seems to be unreachable for this matter.
AElfred itself seems to be OK though, because it comes with an LGPL-style license with an extra clause about linking (which was the main problem between LGPL & ASL).
IANAL so please chime in with remarks.
