How would the tags be delimited then?

Have you considered adding |def: to each tag to make them empty when 
missing, e.g.,

name '${name|def:},${ref|def:},${operator|def:}'

The maximum string length can be exceeded quite easily. Recently, I 
added all routes to my 'routes' style, and ways with multiple 
'${route} ${network} ${ref}' can grow very long names, e.g., 'bus hsl 
731,bus hsl 742,road E 75' etc. instead of '731,742'. It might be better 
to split the information into several layers (maps), one per ${route} 
type.  But unfortunately mkgmap cannot currently generate several maps 
in one run.
