Microformats vs XML, redundancy)

Microformats can be built on HTML 4.0 and newer, because of this there
are a few minor issues that make it difficult to depend on client-side
XSLT. The simplest issues are well-formedness and validity, but simpler
things like <br> being <br/> and <img> being <img/> are all important to
The Microsoft Live Clipboard uses XPATH, but not XSLT on the client-side
so server side, for several reasons.
1) you can clean-up the input
2) you can manage errors better
So to answer your questions:
(1) is this a solved problem? does Microformats encourage (allow) this
--- i don't think this is a solved problem (althought i'm not sure what
the problem really is?) There are several client-side implementations
such as Tails. I think a combination of client-side and server-side
options are important. Server-side options are important for content
developers, by using these web services, site owners can link to them
and have their vCard/iCal/AtomFeeds all created for a user no matter
what their browser. Client-side options are important because they can
be used to find encoded data, and have the ability to extract data that
is behind authentication - something server-side implementations can not
really do. The downside to client-side options is adoption of the tools
to do so. Tails is great for Firefox, but there currently isn't that
support for IE (i don't think IE applies XSLT transformations either?
partly because they do not use the application/xml mime-type - someone
will correct me if i am wrong)
(2) how well is it supported by Microformats tools?
Well if it is client-side then the biggest tool at the moment is
Tails, there are also XSLT files available for download for
hCalendar/hCard/hAtom which can be used client-side.
I hope that helps answer your questions, or at least starts down the
