0045-css Omits conformsTo in use of FragmentSelector #655
Description

Correction request
I was trying to get iiif-prezi3 to implement 0045-css.md, but currently it cannot. That's because the cookbook, JSON schema, iiif-prezi3 library, and W3C Web Annotations is all slightly different.
The W3C spec says conformsTo SHOULD have exactly 1 value. That's a strong recommendation but maybe not a MUST. In the cookbook recipe where FragmentSelector is used, conformsTo is dropped, so even though it says it SHOULD have it, it doesn't. Maybe this is in line with minifying the cookbook recipes.
If you all think this is not required, I will open a request in iiif-presentation validator to drop the "default" from conformsTo in the JSON schema so that it is truly optional.
