On /users/{id}/badges, the description of id parameter diverges from the inferred standard.

e.g.

a semicolon delimited list of user ids

vs

A single primary key identifier or a vectorized, semicolon-delimited list of identifiers.

Is this intentional and is there a difference in the way the parameter is handled vs vectorized ids?

It is my understanding that 'vectorized' means that constituent values must be sorted in ascending order. Is this correct?

UPDATE:

Upon dumping all parameters i come up with these variants:

id  string  A single primary key identifier or a vectorized, semicolon-delimited list of identifiers.
id  string  a semicolon delimited list of user ids
id  string  semi-colon delimited list of post ids

Can these all be treated similarly?

#Conclusion

I got the answer I was looking for and am able to generate code that passes the following tests:

Tags (arbitrary number of strings):

[Test]
public void CheckParamArrayTags()
{
    var client = new SoapiClient("api.stackoverflow.com", "");

    QuestionsTaggedByTagsResponse response = client.QuestionsTaggedByTags("sqlite", "sqlite3", "c#").GetResult();


    Assert.Greater(response.Questions.Count,0);

    Assert.IsTrue(
        response.Questions.All(
            q => q.Tags.Contains("sqlite") && q.Tags.Contains("sqlite3") && q.Tags.Contains("c#")));
}

Ids (arbitrary number of int32)

[Test]
public void CheckParamArrayId()
{

    var client = new SoapiClient("api.stackoverflow.com", "");

    UsersByIdResponse response = client.UsersById(242897, 1).GetResult();

    Assert.AreEqual(2, response.Users.Count);
    Assert.IsTrue(response.Users.Any(u => u.UserId == 1));
    Assert.IsTrue(response.Users.Any(u => u.UserId == 242897));
}
