[Tagging] how to tag small parts of buildings

[Martin Koppenhoefer]

While mapping a medieval village I have found some features I would like to map but am not aware of established tags for them.

These features are generally parts of building facades, for example 

- inscriptions, often initials of former proprietors or restoration dates. Sometimes these are engraved in stone frames of doors, or they are engraved into stones that are inserted into the facade
- particular (original historic) architectonic elements, e.g. a mullioned window in a house 
- other stone parts in the facade (spoils), e.g. consoles, sculptural artwork (e.g. statues holding architectonic elements like oriels, etc.)


as these are parts of the facade and I would like to store their position as well, I don't want to add them as properties to the buildings themselves. Rather they could be ways or nodes, according to their size.


I am interested to learn if someone has already mapped something similar and with which tags, or what you think would be a good representation.


Should I invent a new key facade:part=* ?
Or better use the historic key?

Cheers,
Martin
