It should be emphasized that building a new, complete vocabulary in
microformat terms may be easy in some cases, but may become a
prohibitive in others, see use case #7. (I know it is referred from the
text, but an emphasis on the complexity of the vocabulary may be

I have slightly reformulated the first paragraph. My goal is also to
avoid unnecessary controversies with other technologies...

"Some RDFa use cases may be fulfilled by microformats [MF]. In
particular, Use Case #1 and part of Use Case #2 can be achieved using
hCal [hCal]. In such cases, microformats (possibly commbined with GRDDL)
provide a perfectly appropriate solution. However, in each of the use
cases in this document, the microformat approach requires either
building a new, complete vocabulary, or it should take into account the
*mixture* of several vocabularies in one single application. While this
may be simple in the case of, say, hCal, hCard, etc, this becomes
prohibitive when, for example, large vocabularies are used like in Use
Case #7 or simply when the shere number of vocabularies mixed within an
application becomes too large. RDFa aims to combine, remix, and extend
<em>existing</em> vocabularies easily, thus fully enabling Use Case #2,
Use Case #3, or Use Case #7."
