[possible idiot question] Can DITA 8 live in FM 7?

[Art Campbell]

Has anyone tried creating a DITA document in FM 8, saving as FM 7 MIF,
and then opening in unstructured 7.1 / 2?
Can the 7.x user make text edits (not wholesale reformatting or tag
changes) without trashing the "hidden" DITA structure and data?

Thanks,
Art
