In this preference settings, you can activate only the tests you need. By default, all error and warning tests are active.

These are the validations performed by the validator:

|| [[Image(source:/trunk/images/data/warning.png)]] || Duplicate house numbers || two members of an `associatedStreet` relation have the identical house number. || Make sure different buildings have different house numbers. Ignore this warning, if two buildings really have the same house number. ||
|| [[Image(source:/trunk/images/data/warning.png)]] || Multiple street names in relation || `name` tag of an `associatedStreet` relation matches the `name` tags of the members with role `street` and the `addr:street` tag of the members with role `house`.
|| [[Image(source:/trunk/images/data/warning.png)]] || House number too far from street || the houses of an `associatedStreet` are far away from the corresponding street. || Verify that the house really belongs the the street that is given by the relation. ||

(Ways must be connected end-to-end.) ||
|| [[Image(source:/trunk/images/data/warning.png)]] || Superfluous turnrestriction as "to" way is oneway || The turn restriction is not needed, because the corresponding turn would mean to enter a oneway street from the wrong side. || Verify that the "from" and "to" ways are correctly assigned and delete the relation if it is indeed superfluous. ||

|| [[Image(source:/trunk/images/data/warning.png)]] ||Way end node near other highway|| End point of a way is very near to other ways || Connect the ways or when really unconnected set a 'noexit' tag to prevent further warnings ||
|| [[Image(source:/trunk/images/data/warning.png)]] ||Style for outer way mismatches||Within a multipolygon relation, one of the tags of the relation and the outer ways is shared but with different values||Copy relation related tags to the relation itself||
