+Remove the access rights defined from any matching allow rules. These rules are processed before [`neverallow`](cil_access_vector_rules.md#neverallow) checking.
+
+**Rule definition:**
+
+```secil
+ (deny source_id target_id|self classpermissionset_id ...)
+```
+
+**Where:**
+
+<table>
+<colgroup>
+<col width="27%" />

+ (allow type_3 type_4 (class1 (perm1 perm2))) ; Allow_2
+ (deny type_3 type_4 (class1 (perm1))) ; Deny_2
+ ; Allow_2 will be removed and replaced with the following when Deny_2 is evaluated
+ ; (allow type_3 type_4 (class1 (perm2)))

Looks like theres some intermixing of spaces and tabs messing up
formatting on the example.
