[scim] PATCH "Add" Operation with Value Paths

[Shelley <[e-mail]>]

What is the expected behavior when an "*add*" operation provides a "*path*"
containing a multi-valued attribute with a *value filter*?

In this example, I suppose that any emails that meet the criteria should
set/replace their "type" sub-attribute? (Although, I'm not sure why a
consumer would choose "add" vs. "replace".)
{
    "op": "add",
    "path": "emails[primary eq false].type",
    "value": "other"
}

In this example, however, I'm not at all sure of the semantic meaning of
the filter? Should this be unsupported (resulting in a failure), should the
filter itself effectively be ignored (where the enclosed email element is
just appended to the emails array as if the filter was not provided), or
should this have some other behavior (e.g. some type of attribute merging
for elements that match the filter)?
{
    "op": "add",
    "path": "emails[primary eq false]",
    "value": ...
}
