You can have multiple tags with same name if you reference them using
the parent tag and not wild cards. With the current proposal, if you
test with:
xpath -e '//divecomputer' <file>

you will get the settings and dive samples. //settings/divecomputer
would give you only the settings part. So from XML point of view, this
will work fine. (I am not sure how these are parsed in Subsurface, but
the context should be clear in there as well.)

On the other hand, clarity of the XML might become an issue when using
same tags on different contexts.
