No. XML parsing is difficult to parallelize because you need to parse
things preceding, say, an element in order to know where this element
starts and ends.

XSD-generated parser skeletons are thread-safe in the sense that you
can use several instances in several threads concurrently. This is
possible due to the generated code not relying on any writable global
variables.
