Part 1

Original text:

An assertion MAY indicate that it is an ignorable policy assertion 
(see 4.4 Ignorable Policy Assertions). An ignorable policy assertion is 
an assertion that may be ignored for policy intersection (as defined in 
Section 4.5 Policy Intersection). By default, an assertion is not 
ignorable for policy intersection.

No change.

Change 2

Original text:

If the mode is lax, two policy alternatives are compatible if each assertion in one that is not an ignorable assertion is compatible with an assertion in the other, and vice-versa. 

Revised text:

If the mode is lax, two policy alternatives A and B are compatible:
a) if each assertion in A that is not an ignorable assertion is compatible with an 
assertion in B, and
b) if each assertion in B that is not an ignorable assertion is compatible with an 
assertion in A.

Change 3

Old text:

If the mode is strict Ttwo policy alternatives are compatible if each assertion in one is compatible with an assertion in the other, and vice-versa

Revise for symmetry with Change 2.

Change 4:

New text (add commutative back in)

Intersection is a commutative function that takes two policies and returns a policy.

Change 5: 

This is an optional attribute of type xs:boolean

New text:

This attribute is of type xs:boolean

Action to Editors: Apply to template edit to other cases of "optional element" or "optional attribute".

No objection to Ignorable

Change 7:

There are two modes for intersection: strict and lax. How the mode is indicated for the policy intersection is outside the scope of this specification.

New text:

There are two modes for intersection: strict and lax. How the mode is
selected or indicated for the policy intersection is outside the scope of this specification.
