I think this would work if docs was a group of actual objects. However,
docs is a "lines" Folder property. So, the sequence-item is just a string.
If I say:
<!--#var "sequence-item + '.title'"-->, it will say "test.title".
However, I can seem to get it to actually track down test.title
as if I had done:
<!--#var test.title-->

(BTW, I tried the example you gave and it prints the Folder's title.)
