> The position of optional elements is relavent within the ACIItemParser.  For example
for ProtectedItems the position of optional elements are relevant so for example the following
ACI whould bomb out:
>                 "{ " +
>                 "identificationTag \"searchAci\", " +
>                 "precedence 14, " +
>                 "authenticationLevel none, " +
>                 "itemOrUserFirst userFirst: { " +
>                 "userClasses { allUsers }, " +
>                 "userPermissions { { " +
>                 "protectedItems {allUserAttributeTypesAndValues, entry }, " +
>                 "grantsAndDenials { grantRead, grantReturnDN, grantBrowse } } } } }"

> This however would succeed:
>                 "{ " +
>                 "identificationTag \"searchAci\", " +
>                 "precedence 14, " +
>                 "authenticationLevel none, " +
>                 "itemOrUserFirst userFirst: { " +
>                 "userClasses { allUsers }, " +
>                 "userPermissions { { " +
>                 "protectedItems {entry, allUserAttributeTypesAndValues }, " +
>                 "grantsAndDenials { grantRead, grantReturnDN, grantBrowse } } } } }"

> The same holds for other constructs where a sequence of optional elements are expected.
 However this is a big problem.  The user specifying the ACI must know what comes first, what
comes second and so on in the ASN.1 description.  This is just too strict of a constraint
to place on users and will degrade the ease of use.  
> Really because we have names for each field order does not need to matter anymore.  
> I marked this as an improvement as opposed to a bug because the ASN.1 to ABNF translation
was correct.  It just is not the best thing to do.
