If no unit identifier is specified, the value is assumed to be in degrees. so so 360deg, 0rad, 1000.5, ... should all be valid. THe schema is pretty useless here: <define name="angle"> <data type="string"/> </define> Note though that style:text-rotation-angle currently does _not_ allow arbitrary angles as values: <attribute name="style:text-rotation-angle"> <choice> <value>0</value> <value>90</value> <value>270</value> <ref name="angle"/> </choice> </attribute> I think that is a mistake though. We should allow arbitrary angles here too! Andreas PS: a separate issue is that an angle by itself does not suffice in any or most of these cases. We really should specify which direction is 0deg.
