Medium sized job? Only meticulous when a problem arises. Give me a  
few days to setup a Chicken svn repo entry for the project.

I have a number of goals:

1) Remove "duplicated" code. In the SRFIs, misc-extn, & miscmacros  
eggs much of the support code is available so I want to remove it  
from the SSAX-SXML source.

2) Split into a more modular loading style. As released it compiles/ 
loads as one huge chunk. (Note that this was done for the existing  
Chicken eggs.)

3) Separate syntax & runtime. (Note that this was done for the  
existing Chicken eggs.)

4) Compiler declarations. (Note that this was done for the existing  
Chicken eggs. Although only export declarations, no optimization.)

The export declarations are needed to reduce namespace pollution. A  
problem with the original source. But modularity does result in the  
need for external symbols which are not part of the public API.

5) Reduce the "redefined" messages to 0.

6) Still allow for updates from the official distro.

I suppose the above can be considered a "chicken way."
