CORBA35 — CCM Spec: attributes are listed in the ports section?

In section 1.1.2 of the CCM specification:

1.1.2 Ports
===========
..... The component model supports four basic kinds of ports:

• Facets
• Receptacles
• Event sources
• Event sinks
• Attributes

Well, that list includes five things, not four.

So, is an attribute considered a port or not?

The wording in this section needs to be clarified in the CCM
specification, because it is not clear if an attribute
is a port or not.
