C.1.2 Element angle

C.1.2.1 Description

Allows you to specify an astronomical angle, either in degrees or as an hour angle. All the attributes are (syntactically) individually omissable: the system does not perform any check that the supplied value is reasonable. Example:

<angle angle=45 minutes=30 seconds=10 fraction=0/> is
an angle in 
degrees (the default), and <angle unit=hours angle=6 minutes=45/> is
an angle in hours, with the number of seconds and fractions of seconds
omitted.  An angle like <angle angle=1000 fraction=10/> is
syntactically acceptable, but astronomical nonsense.
