If I understand parser.yy and output-def.cc files, it looks like  
"\Voice" starts you off with a copy of the previously defined Voice  
settings.  If "\Voice" is absent, you start from scratch.

The context settings are saved by name.  If you do not change the  
name, the modified settings replace the previous settings of the  
\Voice context.  If you change the name, a new kind of context is  
created.

I haven't looked into \alias.
