xml statement for check preset

[EtienneChove]

The xml check statement looks like :
<check key="oneway"

text="OneWay"
default="off"
delete_if_empty="true" />

It's not possible to specify tag value. We'd like to provide a preset like :
<check key="shop"

text="With kiosk"
value_on="kiosk"
value_off=""
default="off"
delete_if_empty="true" />

This could be usefull for example for services.

Please provide a real life example. Currently I see no use in supporting what you request.

When tagging a fuel station, I want a check to indicate if there is a kiosk associated with fuel station. If it is checked, I want to add shop=kiosk. If it is not checked, I do not want to add anything.

(In [3279]) fix #4192 - allow definition of true/false values in presets
