The best solution is that the authors of the software that accepts the
parameters
each define the parameters they use. then the central database is
maintained by
scanning those definitions.   This way the database if self maintained and
kept up
to data.

It is never good to define something in two places.  A central XML file is
in effect
keeping the definition in two places, once it it implicitly in the code
that uses the
parameter and again in the XML file Better to place the the entire
definition in one
source file.

How to do this?  Lots of ways, macro processor, function calls or
specialized comments
