Nope, it's a simple "save as". If the document was tagged, it will use 
whatever information as it has about styles, but it doesn't depend on 
tagging to produce valid XML.

My objective is always to get out any proprietary file format and into 
some form of XML as quickly as possible, then assess what I've got and 
move forward from there. You have to tame the data somewhere - I prefer 
to do it in XML but before my target structure.

Yep, I started coding with OmniMark when it was still XTran from 
Exoterica and it's a great tool. If you're doing whatever the modern 
equivalent is to a cross- or up-translate though, the additional 
information in the form of the XML tagging is only going to assist, I 
would have thought. I don't see the two approaches as being incompatible 
at all.

Sure, if you're willing to send your data out you don't care what tools 
they're using, but that wasn't what the original poster was after.

Agreed - identifying sentences and pages is a very different task to 
anything more concentrated on the information.

I wasn't advocating it, but saving as RTF from PDF and then going to XML 
was mentioned. I was offering an alternative.
