NPRML XML namespace link does not return a schema

[benlk]

The NPRML Namespace is xmlns:nprml=https://api.npr.org/nprml, but https://api.npr.org/nprml does not have a schema. Is this intentional?

The present version of the w3c recommendation for Namespaces in XML 1 doesn't require that the namespace URI reference be a link to an active schema doc:

The namespace name, to serve its intended purpose, SHOULD have the characteristics of uniqueness and persistence. It is not a goal that it be directly usable for retrieval of a schema (if any exists).

The entire document at https://api.npr.org/nprml is as follows:

{"error":"This API is not found. For documentation of current API services, please visit the NPR Developer Center."}

https://api.npr.org/ 301 redirects to https://www.npr.org/api/index.

And, should this URL be upgraded to HTTPS?

nprapi-wordpress/classes/NPRAPI.php

Line 21 in f4032ce

const NPRML_NAMESPACE = 'xmlns:nprml=http://api.npr.org/nprml';

Upgrading to HTTPS in #44.

Closing because the namespace link does not need to return a schema, according to the relevant XML specification.
