The current API already supports xs:base64Binary, in the case of a binary type (technically, for all non-text, non-HTML, non-XML types). Which will be the case for a ZIP file (as long as the server returns a correct Content-Type, but you can always overrides it anyway). Is there any intrinsic difference, from an implementation point of view, in the context of streamability of the returned content, between a function returning always an xs:base64Binary item, and another one returning sometimes an xs:base64Binary item, sometimes a string, and sometimes a document node? From what I understand of the implementation strategies, a kind of naive implementation would be to create an alternative implementation of xs:base64Binary, which does not contain the actual bits (e.g. as an array in memory), but rather a handle to a binary stream (e.g. in Java it would contain an InputStream, consumed only when needed). And whether a function will always return such a "binary item delegating to a stream under the scene", or instead will sometimes return such an item and sometimes strings or nodes, it does not seem relevant in this approach, is it? Of course, BaseX might want to provide the user the ability to enable such streaming or not, as it can be a restriction on how to use the binary items (you can read them only once, or pass them only to streaming-enabled functions). I am just trying to see if there is anything that intrinsically prevents streaming in the HTTP Client, or if it is just that some possible implementation strategies have not been investigated. I am pretty sure Adam implemented streaming for the HTTP Client in eXist, so it might be interesting to have a look there as well. That is indeed a very interesting feedback, thank you!
