There is a behaviour of xmlconcat that I do not understand. Calling as \xmlconcat{#1}{test}{xxx} correctly interjects the "xxx" between the successive members, in according with the documentation. But using the command version for calling: \xmlconcat{#1}{test/command(xmltest:test)}{yyy} does typeset the nodes but not the text from the third argument. It might be the correct behaviour but it confuses me. Any comments or enlightment? Thamks in advance.
