I can't speak for the documentation. Usually the difference between them is just not relevant most of the time. The terms are not truly interchangeable but most of the time people known what you mean. If you want to hurt your head read the IETF RFCs on this. I cannot recommend this practice for its entertainment But here is a bit on URI, URL, URN from the IETF RFC 3986. This has been superceded but this gives a better explanation of the differences. In the end it says use URI everywhere in later standards which then does in fact seem to happen. https://tools.ietf.o...6#section-1.1.3
1.1.3. URI, URL, and URN
A URI can be further classified as a locator, a name, or both. The
term "Uniform Resource Locator" (URL) refers to the subset of URIs
that, in addition to identifying a resource, provide a means of
locating the resource by describing its primary access mechanism
(e.g., its network "location"). The term "Uniform Resource Name"
(URN) has been used historically to refer to both URIs under the
"urn" scheme [RFC2141], which are required to remain globally unique
and persistent even when the resource ceases to exist or becomes
unavailable, and to any other URI with the properties of a name.
An individual scheme does not have to be classified as being just one
of "name" or "locator". Instances of URIs from any given scheme may
have the characteristics of names or locators or both, often
depending on the persistence and care in the assignment of
identifiers by the naming authority, rather than on any quality of
the scheme. Future specifications and related documentation should
use the general term "URI" rather than the more restrictive terms
"URL" and "URN" [RFC3305].
I interpreted the accord:/ as describing how to access the resource thus rendering this a URL. It identifies the primary access method, via Accordance, just as http:// does for web addresses.
But really don't worry about the difference, you will go mad
