I agree with separating orthogonal characteristics of crossings into
different tags. A single tag cannot easily express both the presence of
traffic signs and the presence of markings.

However, it seems odd to "demote" traffic signals to a sub-tag when
their presence or absence is perhaps the biggest influence on the
crossing's overall character.

In comparison, it seems somewhat less important whether a signalled
crossing also has painted markings on the road. So I would suggest using
a separate tag for the markings instead. We need a tag for the _type_ of
the markings anyway (as different patterns for marked crossings can have
entirely different legal meanings in some jurisdictions), and we can use
that same tag for presence/absence by also allowing yes/no values.
