There is no such beast.  These were originally intended to be purely internal 
objects.  If we decided to expose them as an API, we'd want to decide on the 
naming (Martin doesn't like the "Parsed" prefixes, I'm +0 on killing them) and 
document them properly.

For now, your best bet is to have a look at XPath/Parsed* in 4Suite (and also 
check out Xslt/Parsed* for the associated Pattern machine objects).

Hmm.  I looked into this, but I'm not seeing it.  I went as bare-bones as 
possible to avoid user agent artifacts and all that:

As you can see, the meta refresh goes to the relative "index.epy".  I don't 
know how this would cause the effect you mention.  What user agent are you 
using?

Thanks.
