Some of them do, but most of them don't. And even those that do, 
their usage of 'ontology' covers both kinds of box. OWL is used for 
any kind of data, T or A. The distinction is meaningless in any case 
when applied to a logic, and has not been seriously used even by the 
description logicians for about a decade now.

In fact, it can only be used for making assertions, since there is no 
definition syntax in SCL or FOL (or OWL for that matter)
