Alert Schema to be updated
The alert schema in the "Alert Content" section seems to be outdated, when compared to the examples in _static. Some possible issues:
- the possible values of "search" in the schema are "CBC" and "Burst", while the examples have "MDC";
- there is no P_astro in the schema (it is missing also in the example notices, actually...);
- the "Sky map" parameter is actually "GW_SKYMAP" (I think we should keep the same parameter names as in the actual notice);
- some relevant parameters are unlisted, such as "AlertType", "Retraction", "Vetted", "EventPage".
