Subject: [xri] XRI Resolution 2.0 Draft 10 comments

Hi all,

My questions regarding the newly submitted draft are below:

1. Section 4.2.2 - Line 511 states that "Parameters specified in this manner
SHOULD take precedence over the same parameters provided via any other
interface". Of the 3 optional resolution parameters, if only 1 is provided
in the HXRI, the values of the rest should be considered as null or other
interfaces (such as HTTP header) should be considered?

### Yes. The rule should be: if the parameter is supplied in the QXRI, then
it takes precedent over the parameter supplied via any other interface. This
includes null parameters, i.e., if the QXRI includes a parameter that
explicitly sets a null value, then the parameter should be set to null.
However if a parameter is completely absent from the QXRI, but is supplied
via another interface, the parameter value should be accepted from the other
interface. ###

2. Section 5.6 - Flowchart suggests that the value of xrd:XRD/xrd:Service/
xrd:Path should be equal to either Path OR "(" Path ")", in order for the
service to be selected. Whereas the normative rules for the algorithm, pt. 4
says that the selection of a service should be *repeated* with the value of
path = "(" Path ")". So, is there an EQUALITY or a PRIORITY relation between
the path values distinguished by parenthesis?

### Great point. It should be an EQUALITY relation. As a result, if you had
the following two Service elements...

	<Service>
		...
		<Path>+contact</Path>
		...
	</Service>

	<Service>
		...
		<Path>(+contact)</Path>
		...
	</Service>

...then if the QXRI path value was "+contact", it would select BOTH of the
above services as equally matching this path.
