A bigger question is whether they are all correct. This one at least seems
wrong, because it has no check for text nodes:

listitem[formatinfo][count(child::*) = 1]

Yes - I missed the "or text" part of "no other element or text". As the OP said it seemed to work, so they didn't spot it either... It goes to show how easy it is to create incorrect results that look right with XSLT.

Btw, shouldn't your suggestion of:

select="listitem[node()[last()=1][self::formatinfo]]"

really need to be as a template match rather than select:

match="listitem[node()[last()=1][self::formatinfo]]"

?
