Description

The following schema:

  price:
    title: Price
    type: number
    format: decimal

generates a error, unknown format decimal for type number

Why not support it, converting to "number" type?

Done means the schema is accepted and decimal is treated as number without the unknown-format error; add or update coverage if the relevant test location is found.
