I read this thread, I think there's too much misunderstanding and offtopic
issues to get something meaningful out of it.

I think you nailed it, much of the misunderstanding and our disagreement comes
from this tag.
I understand the key designated as : this way has been made specifically for
this vehicle, it should be used in priority before the surrounding ones.
What do you think designated is used for ?

Following this definition, a way tagged with (highway=bridleway &
horse=designated) has redundancy because a bridleway is, by definition, made
specifically for horses.

Agree

> highway=cycleway & mkgmap:country=FRA  { add foot=yes }
Disagree. In French law, a cycleway is not allowed to pedestrians unless signed
otherwise.
highway=cycleway & mkgmap:country=FRA  { add foot=no }
(if this rule is not already applied by default in mkgmap, I don't know the
default ones, are they posted somewhere ?)

> highway=bridleway & mkgmap:country=FRA { add bicycle=yes; add foot=yes }
Agree

Of course, these rules are to be applied at the beginning of the mkgmap
processing so a superseding attribute (for example foot=yes for a cycleway) can
be applied correctly.
