i4i's patent (issued in 1998) looks a lot more specific than that to me.
The essence of the invention is that formatting / structure metadata
is stored separately and mapped against the text content based on
character position rather than, as per usual practice, embedded in the
content as tags. For example, the same text content could be displayed
as an 8.5" x 11" print document or an online help system by applying
two different metacode maps, rather than the usual approach of
generating two new documents with different sets of embedded codes.
The patent says, "In SGML this ability to overlay two or more
structures on a single set of text is called Concur. Its usefulness
has long been recognized but it has proven difficult to implement."
The last few pages of the patent go into excruciating detail about
i4i's method for doing that:

I did read the initial blurb and waded through a little of the deeper statements. It looks suspiciously to me like the patent says, "Here's a new idea... We'll use XML to represent documents in an application-specific way!" ...
