Implicit OSCAL namespace and profile resolution

[galtm]

The schema documentation (e.g., for prop/@ns) says, "When a ns is not provided, its value should be assumed to be http://csrc.nist.gov/ns/oscal and the name should be a name defined by the associated OSCAL model."

The profile resolution spec says, "The remove directive criteria ns-ref MUST match an object if and only if its value is identical to the value of that object's ns child" (where ns-ref should say by-ns; see #1246).

1. Is the ns assumption intended to be in effect during profile resolution, so that <remove by-name="x" by-ns="http://csrc.nist.gov/ns/oscal"> would target <prop name="x" value="y"/>, for instance? If so, can the profile resolution spec please mention this behavior?

2. Can someone confirm that <remove by-name="x"> without @by-ns should target any of the following?

<prop name="x" value="x"/> <!-- implicitly OSCAL -->
<prop name="x" ns="http://csrc.nist.gov/ns/oscal" value="x"/> <!-- explicitly OSCAL -->
<prop name="x" ns="http://something.org" value="x"/> <!-- not OSCAL -->

Thanks!
