[dxwg] Is one of dcat:accessURL, dcat:accessService and dcat:downloadURL required in a dcat:Distribution? (#1197)

== Is one of dcat:accessURL, dcat:accessService and dcat:downloadURL required in a dcat:Distribution? ==
Hello DXWG,

At Europeana, we are designing a profile where we need to use the class dcat:Distribution without using any of the three properties dcat:accessURL, dcat:accessService and dcat:downloadURL.
Question: Is this a correct usage of dcat:Distribution? Or one of the three properties should always be stated?

We felt unsure after reading the [DCAT 2 latest editor draft](https://w3c.github.io/dxwg/dcat/).
I believe these are the passages that made us unsure:

The dcat:Distribution states in the last paragraph of section 6.7:

> Links between a dcat:Distribution and services or Web addresses where it can be accessed are expressed using dcat:accessURL, dcat:accessService, dcat:downloadURL, as shown in Figure 1 and described in the definitions below. 

In the usage notes for these three properties, it is writen:

> dcat:accessService SHOULD be used to link to a description of a dcat:DataService that can provide access to this distribution.

> dcat:accessURL SHOULD be used for the URL of a service or location that can provide access to this distribution, typically through a Web form, query or API call.

> dcat:downloadURL SHOULD be used for the URL at which this distribution is available directly,

Many thanks in advance.

Kind regards,
Nuno
