One thing which I've noticed as I've written customer facing apps in
XQuery is the inability to stream a dynamically constructed XHTML page,
RSS feed, etc. from the MarkLogic server.  In other words, the entire
page/response must be built in memory before the first byte can be
shipped to the client.  In some situations, this can be resolved by
better page design, AJAX, etc. but this is always not practical.  I'm
not really talking about the ability to support 'byte serving' for
binary content (such as PDFs) ... that is a completely different
scenario (which of course others might find beneficial if it were
addressed).   I also understand this might be attributed to the XQuery
specification and how things need to operate (well-formedness, etc.);
but, on the other hand proprietary extensions are frequently added by
vendors.   So, I'm curious whether others have encountered this
situation and perceive it as an issue for developing customer facing
apps in XQuery.
