Hi Ralph,

Yes, ok.  But I had stated that it is not specified in CSTR54 that macro 
contents can be accessed via \*(xx and that a string defined with ".ds xx ..." 
can be accessed with ".xx".  ยง7.1 does only say that there can't be a request, 
a macro or a string with the same name at the same time.  Nothing else.  It 
does not anyhow document whether a string and a macro have the same data type 
or the same internal representation (which is indeed documented in the groff 
manual).  Yes, it is imlemented that way, but if it's not documented it can't 
be used (in traditional troff).

Yes.  But does this say that the diverted data can be accessed via \*(xx?

(As I said this is done in historical mdoc but does not work reliable.)
