Yes, that is one example. A few other implementations have similar extensions. 
However, I think the best example is Jekyll [1], the static file generator 
behind GitHub Pages (admittedly, Jekyll is not a markdown parser, but a tool 
that uses one). Although its metadata syntax is not really that much different 
that the other metadata extensions, it is important to note that Jekyll 
supports more than one text format (markdown, textile). Behind the scenes, the 
code removes the "frontmatter" first (which is passes on to a YAML parser), 
then passes the remaining text on to the appropriate parser. The point is that 
the one file contains 2 documents: a YAML document and  markdown document; each 
parsed by a separate tool. So, while other markdown parsers may parse the 
frontmatter with the same tool, I still think of the metadata as being 
something other than markdown.

I should also point out that a number of projects will use the first <h1> 
Header in the document as the title. And if the file is stored on the file 
system, the creation and modification date may be pulled from the file system.  
Some even use the file name for the title (converting underscores to spaces and 
title casing). But those are the least flexible systems. The most flexible 
systems generally store the metadata in separate columns in a database 
alongside the markdown.

One thing is for certain, there is absolutely no standardization regarding 
metadata associated with markdown documents and many (most?) parsers do nothing 
to address the issue.

IMO, pure markdown is just human readable HTML fragments. That, I guess, is 
part of the reason why I asked why we need a mime type way back in my first 
response. Those HTML fragments don't really stand on there own, so why would a 
pure markdown file be transported on its own outside of some container that 
contains all that other metadata? Especially when that container already has a 
mime type of its own.
