XMI_FILE_VERSION shall not have #ifdefs attached.
It shall be a single, unique version string which is only incremented
when the XMI format is changed.
It is exclusively related to the loadFromXMI/saveToXMI functions.

Whether Umbrello can act upon the added XMI tag or attribute reliably
and in the desired manner is another matter.
That does not belong in the XMI_FILE_VERSION but in the UMBRELLO_VERSION_STRING.

I propose extending the <XMI.exporter> tag to contain the
    <XMI.exporter>umbrello uml modeller 2.31.70-a9d91d68a

If a certain Umbrello version has a problem in the load/save functions
then it shall be possible to know the version just from the XMI files
attached to the bug reports.
