{{/*

  Render a table listing the properties of an object, given:

  * `title`: optional caption for the table

  * `anchor`: optional HTML element id for the table

  * `properties`: dictionary of the properties to list, each given as:
    `property_name` : `property_data`

  * `required`: array containing the names of required properties.
    In some cases (such as response body specifications) this isn't used, and
    instead properties have a `required` boolean attribute. We support this too.
