But this OOB data is lost when a file is saved to disk. Or are any
applications already using some tagging in the OOB data of the filesystem?
Really, I've never thought of it, how does IE handle this when saving files?

One would expect that the priority is, low from high, OOB, BOM, meta, which
is also the natural order of processing, meaning each directive would simply
override previous ones. And not retroactively. Although, yes, a disagreement
between BOM and meta could be problematic.

Could even be, theoretically. As long as each directive only applies for the
data that follows it, possibly with the first one being an exception to the
rule. But I guess there is no need for it.

This being the reason for my mentioning an exception to the rule.
And, thanks for the info, Jon.
