Limit (in bytes) on maximum size of an XML-based request
+- body. A value of 0 will disable any checking.
++ Limit (in bytes) on the maximum size of an XML-based request
++ body. A value of 0 will apply a hard limit (depending on
++ 32bit vs 64bit system) allowing for XML escaping within the bounds of
++ the system addressable memory, but it exists for compatibility only
++ and is not recommended since it does not account for memory consumed
++ elsewhere or concurrent requests, which might result in an overall
++ system out-of-memory.
