Thanks for the hints. I can finally agree it’s a bug ;) I have added a
GitHub issue for it [1]. The problem only occurs with "database nodes"
(which are the ones created via "fn:doc", "fetch:xml", or by applying
transformations via "copy $c := ..." or "... update {}".This looks to me like a generall weakness of the EXPath spec in general: A namespace declaration will always be valid for all descendant nodes of an element. As it doesn’t make sense to keep the http namespace when supplying bodies via http:send-request, we are explicitly removing the namespace from the body node before sending it out. As there is no such functionality in XQuery like “removing namespaces”, this operation is not well-defined, and it’s probably the reason for this bug. I hope I’ll find time to fix this soon.
