Here is my review of the Profiles specification:

Overall comments:

Despite some minor concerns listed below, the spec is ready to go.

Detailed comments:

Section 1: Introduction.

The last paragraph of the introduction says 'This document depends on the 
four features identified in the OWL 2 Specification [pointer to the syntax 
spec] as being at risk'. However, I could only find two features at risk 
in the Syntax Spec (Feature at risk #1 owl:rational support and Feature at 
risk #4: rdf:XMLLiteral support, which should probably be numbered 2)

Section 4.1: OWL 2 RL Feature overview.

NegativeObjectPropertyAssertion and NegativeDataPropertyAssertion are 
disallowed, but it seems that they should be part of the language since 
they can be expressed using other allowed constructs (e.g. 
NegativeObjectPropertyAssertion(R, a, b) = 
DisjointClasses(ObjectSomeValueFrom(R, ObjectOneOf(b)), ObjectOneOf(a))). 

Section 4.2.5 OWL 2 RL Axioms

DataPropertyDomain is incorrectly defined as DataPropertyDomain := 
'DataPropertyDomain' '(' axiomAnnotations DataPropertyExpression 
superClassExpression ')'. superClassExpression in the previous definition 
should be replaced by DataRange.
