2.2.1 Properties order of listing - STIX Part 1

In the table under 2.2.1 Properties, we read description, url and external_id are all optional. Then, in 2.2.2 Requirements, we read:

*****
In addition to the source_name property, at least one of the external_id, url, or description properties MUST be present.
*****
which is the reverse of the order of the table in 2.2.1.

That may seem like a minor point but anyone hurriedly reading a table needs all the help they can get. Use the table order and revise.
