Revert "Add support for parsing of large XML data (>= 10MB)" This reverts commit 2197d06224a1, following a discussion over a Coverity report where issues like the "Billion laugh attack" could cause the backend to waste CPU and memory even if a client applied checks on the size of the data given in input, and libxml2 does not offer guarantees that input limits are respected under XML_PARSE_HUGE.
