> We use the WriteSchemaToFile task to store our applications schema in a file we place in our Subversion CM tool.  Every time we run this task, it reorders the foreign keys on a table.  So, for example, if Table A has FKs X, Y, Z then schema.xml file alternates between:
> <table ...>
>    <fk name='X' .../>
>    <fk name='Y' .../>
>    <fk name='Z' .../>
> </table>
> AND 
> <table ...>
>    <fk name='Z' .../>
>    <fk name='Y' .../>
>    <fk name='X' .../>
> </table>
> Notice, that the keys haven't changed between schema dumps, just the ordering of them in the file.  This means tracking version changes is more complicated as a developer's real changes are mixed in with these spurious key position changes.
