Provide a way for a field to "look at sibling tags"

[tordans]

Description

Goal: For tags like parking:left|right|both=* it would be great if the directionCombo field for parking:left|right|both:orientation could "look at it's sibling tags". This would improve the mapper UX and likey data quality by showing smarter placeholder or disabling fields alltogether.

Example 1:

Field parking as parking:left=no|separate
In this case, the directionCombo for orientation should …

• disable parking:left:orientation
• or change the placeholder to something like "not expected due to parent tag"

Example 1:

Field parking as cycleway=lane + oneway=yes
In this case, the directionCombo for cycleway should …

• change the placeholder for cycleway:{backward} to something like "implicit 'no' due to oneway"
  I now see, we would also have to evaluate the direction of the way in order so know if "left" or "right" is meant
