You can include this version information into the generated header
file using the prologue/epilogue mechanism (see the --hxx-prologue-*
options). For example as a constant:

const unsigned int schema_version = 11;

You can extract the version information manually (in which case
you will need to update your build scripts/makefiles every time
the version changes) or you can create a small program or script
that parses your schema as XML and automatically extracts the
version information. This program/script can generate the above
version constant into a file which can then be included into the
generated header with the --hxx-prologue-file option.
