I think “simple” is debatable when it comes to walking through an AAF composition and MOB structures… that being said, if all you want is a list of clips and timecodes, a simple EDL, or an XML from FilmScribe, or using the set bin display of a sequence and export as TAB may be a better method at this time to achieve what you are trying to do.
Note that the FilmScribe XML is just that – a representation of FilmScribe lists as XML to make it easier to parse. If someone wanted to write XSL to turn it into FCP XML, or other type of XML, then that work would need to be done. Also, XML is export only, not import back into Media Composer.
Again, I am not disagreeing to the simplicity of XML, but dealing with how it works now as it stands.
