Re: [sca-policy] Issue 26 - final proposal

Good comments.

a)

1) I always read that section knowing that there's MUX in play.  This
is

why we review other people's work. I tried to address it in this new

version.

2) This is a typo, maxoccurs should not be there.

b)

1) same as a1.

2) same as a2.

Dave,

I am still a bit confused by the proposal and I hope that this email will

pinpoint the problem and lead to a

quick resolution.

The problem I have concerns the complex type definitions for

SecurityIdentity and for Authorization.

I am assuming that:

a) SecurityIdentity

can

EITHER be a single useCallerIdentity element

OR a single runAs element

- this is implied by the <choice> element at line 204

What is confusing is:

1) the text following 31 does not say this - I think that it should, to

make things clear

2) the useCallerIdentity declaration at line 206 uses "maxOccurs=1"
while

the runAs declaration

at line 207 does not.  Typically a <choice> implies the use
of 1 (and 1

only) of the elements inside

the choice.  So I deem the "maxOccurs=1" as redundant -
it should be

removed.  Its presence on

one element within the choice and not on another implies some difference
in

treatment of those

elements which does not in fact apply.

Or have I got this wrong and you want to allow or multiple runAs elements??

b) Authorization

I assume that the required behaviour is that the Authorization element

contains 1 and 1 only of

the following child elements:

<allow/>

<permitAll/>

<denyAll/>

1) It would be useful if the text around line 50 said this - for clarity.

2) The schema in lines 220-223 uses "maxOccurs=1" for the child
elements

inside a <choice> element.

The use of choice implies the use of 1 and 1 only of one of the child

elements - so the "maxOccurs=1"

are redundant - and confusing since they make the reader ask "why
are they

there?".

Or have I misunderstood the reason for them being there?

Yours,  Mike.
