man(7) <-> mdoc(7) (approximate) correspondence table?

Hi all,

As someone who's much more familiar with mdoc(7) than man(7), is 
there an approximate 'correspondence table' somewhere that gives 
at least a rough sense of which man(7) macros to use when, in an 
mdoc(7) context, one would use a given mdoc(7) macro? Such a table 
might look something like (to use some obvious probable 
correspondences):

| mdoc(7) | man(7) | Notes
+---------+--------+-------
| Lk      | UR     |
| Op      | OP     |
| Sh      | SH     |
| Ss      | SS     |
| ⋮       | ⋮      | 

i recognise that there's no bijection in general, and that 
specific mappings might differ between projects (e.g. the Linux 
man-pages project might use a certain man(7) macro where a 
different project uses another), but even a project-specific table 
would be helpful to me.

i thought there might be such a table in either groff_man(7) or 
groff_man_style(7), but nothing leapt out ....
