Hello, It is not clear from the specification what the name of the query node of an IQ may (or should) be. In RFC 3921, it is implied that it is "query". However, there's no mention of whether this is a mandatory tag name or not. Because of that, and because there's no example of any other tag name in the whole RFC, I would tend to believe that it is indeed the only expected tag name. However, several XEPs use another one, for example 'vCard'. I think the expected name is actually described in the definition of the corresponding namespace, which would mean that as far as the RFC is concerned, any name is in fact allowed, provided it honors the namespace's definition. Am I right? In any case, we should maybe clarify this detail in the specification. I think several generic IQ-handling implementations rely on the tag being called "query", which breaks their behaviour in case the query tag has a different name. One example is xmpppy[1], but there might be existing or future others if the situation stays unclear. As a related note, it doesn't seem clear either how many direct children an IQ stanza is supposed to have. All examples in the litterature show only one, but I can't see that defined anywhere.
