Donec a diam lectus. Sed sit amet ipsum mauris. <> Vivamus fermentum semper porta. Nunc diam velit, adipiscing ut tristique vitae, sagittis vel odio. Maecenas convallis ullamcorper ultricies. which results in: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec a diam lectus. Sed sit amet ipsum mauris.

Vivamus fermentum semper porta. Nunc diam velit, adipiscing ut tristique vitae, sagittis vel odio. Maecenas convallis ullamcorper ultricies.

===^^^ so the duplicates in the output there are apparently a problem. i am not sure why, unless a link needs to point to each. perhaps so that the reader of the web page can point to each? but as you say, generating the document again foils that plot.
