<p>
A content map of API-specific key-value pairs describing the targeted API entity. The map must be encoded as a
JSON string, e.g., <code>"{ \"description\": \"The API does ...\" }"</code>. Only OpenAPI-compliant
documentation-related fields from the properties map are exported and, hence, published as part of the API entity
definitions, while the original documentation parts are exported in a OpenAPI extension of
<code>x-amazon-apigateway-documentation</code>.
