file format changes

>> Hello,
>> I have read that you are expecting to finalize the file format in
0.9. As expected, it is not possible to read in a 0.6 file when using
0.7. Looking through the files, I could not see any major differences
between the formats (and params, etc).

have problems reentering all the data each update. Is there any way to
help us upgrade the files for release update?? For example, at the
lowest level it would be possible to edit the XML files if you could
give the field changes. A better solution is ,obviously, and upgrade
program.

===============================================
The error seems to be in the 0.6 file. This error comes when I run
against the 0.6 file. The 0.7 file has no error.

No declaration for attribute default_group of element resource-groups
Document mrproject/test.mrproject does not validate against
/usr/share/mrproject/dtd/mrproject-0.6.dtd
