	Thanks for all the hard work.

	I think we need more discussion before changing modus oparandi on verse 
rendering for all clients of the API.

	A few bylaws we've adhered to which are valuable to the users of the 

	o	A client of the engine should only have to render Bible verse numbers 
in 1 way (possibly 2-- for an exception like alternate versification-- I 
think done with footnotes thusfar); we shouldn't expect them to have 
checks in their code for a variety of methods.

	o	We shouldn't expect a client to know the base markup (even OSIS).  We 
do the hard work to hand them something they've requested on init of the 
lib (previously by subclassing SWMgr and applying appropriate filters, 
and now with your newer SWMarkupMgr, which more nicely isolates them 
from the plethora of filter combinations).

	I think these are valuable things which we might be violating with your 
latest changes.  Is there a way to provide filtering in OSIS* filters to 
retain these benefits?

	Up until now, I've had the personal opinion that we should normalize 
OSIS modules to our internal OSIS methods of markup, so filters could 
all expect constructs in the document to be encoded consistently.  We 
have a filter OSISOSIS (which is a silly name) which is intended to 
filter 'our OSIS' markup back to the 'original OSIS' markup of the 
document.  It is used primarily to remove non-conformant tags like 
<resp> in our KJV module, or any other thing we might add to help our 
rendering process, but doesn't either conform to the OSIS standard or 
recommended guidelines, like restore x-preverse titles to their original 

	Again, thanks for the work.  It's nice to have someone finally update 
our OSIS support.  Just want to maintain integrity of these features, if 
we can.
