Dear all, we have now added documentation to function items [1] and higher order functions [2] in our Wiki. These features are being introduced with XQuery 3.0, and they provide much more powerful ways to write real functional code with XQuery. We dare say that BaseX currently offers the most complete and up-to-date support for these new features! Thanks to our team member Leo, we will soon be able to offer the last pending 3.0 features, such as general flwor expressions, which allow an arbitrary order of FLWOR clauses (fot, let, order, group by, count, etc.) [3] By the way: BaseX 7.2 will be released in about 10 days. Stay tuned..

That's very good news! Once again, BaseX is proving itself as one of the most standard-compliant XML databases available! Do you have any result of the W3C test suites, in order to see the coverage of the current support?

That's great news! I am not sure if it was included in the bug/issue list, but we talked about it: Will the issue concerning strange behaviour of ftor be solved with 7.2 or do I have to come up with a workaround to make all possible queries explicit? Best regards Cerstin

we are frequently running the W3 XQuery and Q3 Test Suites to check our conformance (the test classes are part of the open source code, too). Currently, most pending bugs are due to the extended regular expression features that (..unfortunately..) are not supported by Java's standard regex library. Michael Kay decided to embed a new Regex library for that in Saxon [1], which is something we may do as well. It will be exciting to see which implementation will first reach 100%.
