Here in France we tag our town with 2 things :
a node (place=town or village, depending on population size)
a relation (type=boundary + boundary=administrative + admin_level=8)
The relation has members :
outer/inner composed with ways that define the boundary (a closed way
defining an area)
and a node (role=admin_centre) defining the node (place) that is the
center of the town (usely the main place in the town, an indicator for
rendering the name for example.
Here's in example (City of Cognac in France) :
We do not use anymore the key boundary for ways, relation are far more
powerful (but a bit more confused to used at the beginning).
OSM wiki references :
OSM Inspector can help you to check boundary relation (anr more more
beta.letuffe can also display boundary relation (admin 4, 6, 7 and 8) :
