Supports the standard [ [[SerializationOptions serialization options]] ]

If no files are specified, then stdin is read.
If a -w argument is given the output files are wrapped with the supplied container element instead of the root element of the input.

Output files are created by reading up to the root element, and replicating that markup including either the root element,
the wrap element or no root element, then for each (n) child element(s) of the root creating a new xml file with the common header

If the -n flag is used (do not wrap children) then "-c 1" is presumed. Namespace nodes, if any, from the root element will be copied to each child element which will become the document root of each split file.

Implementation Note: xsplit is designed to work with large files. All processing is done in streaming mode on both input and output. This means xsplit can split up files with input *and output* exceed available memory. The side effect is that the options are limited. Arbitrary xpath expressions cannot be used to determine the split points or output files names. Consider combining with the [[CommandXQuery xquery]] or [[CommandXmove xmove]] command to further split files or rename once they are manageable size, and with [[CommandXmove xmove]] to rename the files to a more usable name based on information within the resulting file.
