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. ++
