[NTG-context] \documentvariable (used in environment)

Thank you all.

No modes, no funniness in the environment file.

The test case works (Acroread/properties shows the Title, Author, 
Subject, and Keywords fields). However, my real case does get the other 
fields (Author, Subject, and Keywords) but contains in the Title field 
the filename (without the .tex extension) of the main file (and 
filename.tex under File).

I'll chase it down...

>>> The above example does work. It fails to set the metadata if one moves the \setupdocument to an environment file. As you write, "everything has to be in the same file".
