Example validation issue:- uc06_3d_annotation.json #2439
Description
Currently the example from Configured Scene has a spot light defined as:
{
"id": "https://example.org/iiif/3d/lights/1",
"type": "SpotLight",
"label": { "en": ["Spot Light 1"] },
"angle": 90.0,
"color": "#A0FFA0"
},
But Angle is defined as:
"The value must be a floating point number greater than 0 and less than 90, and is measured in degrees. "
From https://preview.iiif.io/api/prezi-4/presentation/4.0/model/#angle
Should the text be changed to be less than or equal to 90 or the angel in the example changed?

Greater than 0 less than or equal to 90. Need to work on text of angle relating to field of view. Draft:
“The angle property of Spot Lights and Spot Audio Emitters defines the dispersion of the cone of emitted light or sound from its direction. In other words, the angle extends from the center of the cone to the edge of the cone (the half-angle).”
Allowing equal to 90: IIIF/api#2439
