if-op-attr

<if-op-attr> performs a test on attribute values in the current operation.

operator	Returns true when...
available	there is a value available in the current operation (<add-attr>, <add-value> or <attr>) for the specified attribute. Available would return false if there is only a <remove-value> or a <remove-all-values> value for the specified attribute.
changing	the current operation contains a change (<modify-attr> or <add-attr>) of the specified attribute. Changing would return true if it is an <add-attr>, <add-value>, <remove-value>, or <remove-all-values> operations for the specified attribute.
changing-from	the current operation contains a change that removes a value (<remove-value>) of the specified attribute that equals the content of the condition when compared using the specified comparison mode. If mode="structured" then the content must be a set of <component>'s, otherwise it must be text.
changing-to	the current operation contains a change that adds a value (<add-value> or <add-attr>) to the specified attribute that equals the content of the condition when compared using the specified comparison mode. If mode="structured" then the content must be a set of <component>'s, otherwise it must be text.
equal	there is a value available in the current operation (other than a <remove-value>) for the specified attribute that equals the content of the condition when compared using the specified comparison mode. If mode="structured" then the content must be a set of <component>'s, otherwise it must be text. Supports variable expansion.
lt	there is a value available in the current operation (other than a <remove-value>) for the specified attribute that is less than the content of the condition when compared using the specified comparison mode. If mode="structured" then the content must be a set of <component>'s, otherwise it must be text. Supports variable expansion.
gt	there is a value available in the current operation (other than a <remove-value>) for the specified attribute that is greater than the content of the condition when compared using the specified comparison mode. If mode="structured" then the content must be a set of <component>'s, otherwise it must be text. Supports variable expansion.
not-available	available would return false.
not-changing	changing would return false.
not-changing-from	changing-from would return false.
not-changing-to	changing-to would return false.
not-equal	equal would return false.
not-lt	lt would return false.
not-gt	gt would return false.
