#20 Redline Markup support
Redline is the xml markup language that allows
users to annotate drawing files (as if in a seperate
layer).
Although it's saved as XML files which are readily
readable, the schemas for these files (the
validation routines, definition of data types, lengths
etc) are not published.
Looking at the source for the readline files (.rml)
there are three validation documents that have not
been released. These are
RedlineXML_v_002.xdr
VoloView_v_001.xdr
RMLFilterAcDb_v_001.xdr
Getting redline support into lx-viewer would consist
of
1. Making a simple output cpp file which outputs a
.rml file with variables substitued in. (done:
redline.cpp and redline.h)
2. Replicating the three .xdr files ( 1/3 done
VoloView_v_001.xdr)
3. Checking as many outputted .rml files from
Autodesk producks as possible against the .xdr
files to check data types, lengths etc are correct.
I've assigned this to myself and hope to have all
xdr docs finished by next week.

This is probably the most useful thing to be added along with
the AutoCAD 2004/2005 file format conversion.
