Cameron,
thanks once again for contributing your expertise and time.
given that we are now agreed, I propose to query this reasonably
significant issue with the SVGWG.
I hope you will comment and contribute to the resolution.
regards

Hi Jonathan.
Jonathan Chetwynd:
you state:
Invalid values in xlink:href="" are one way of making a
<use> element in error.
but where is the evidence for your assertion?
I thought I had provided it in a previous e-mail
(http://markmail.org/message/7s2biahkzmv6pkxu):
The following rules apply to the processing of invalid URI
references:
* An invalid local URI reference (i.e., an invalid references to a
node within the current document) represents an error (see Error
processing), apart from the xlink:href attribute on the 'a'
element and the properties that allow for backup values in the
case where the URI reference is invalid (see 'fill' and
'stroke').
* …
— http://www.w3.org/TR/SVG11/struct.html#HeadOverview
but looking over that quote again I see I overlooked the word
“local”.
So I agree that my assertion is incorrect, if
externalResourcesRequired="true" has not been specified on the
document:
* When attribute externalResourcesRequired has been set to true on
the
referencing element or one of its ancestors, then an unresolved
external URI reference (i.e., a resource that cannot be located)
represents an error (see Error processing).

SVG doesn’t seem to require any particular behaviour in the case of
a
missing external resource when externalResourcesRequired="false".
