In Savannah we agreed that in the operations get-job-attributes, get-jobs, and get-printer-attributes, if the 'requested-attributes' attribute contains values specifying attributes not supported by the printer, the printer SHALL return status code 'successful-ok-ignored-or-substituted-attributes' and MAY return these attributes in the 'unsupported-attributes' group.  My question is, if the printer chooses to list the attributes as unsupported in the response, which of the following formats should it use (suppose the printer doesn't support 'printer-info' and 'printer-location'):

attr-tag=value-tag-unsupported
attr-name='printer-info'
attr-value=NULL

attr-tag=value-tag-unsupported
attr-name='printer-location'
attr-value=NULL

- or -

attr-tag=value-tag-keyword
attr-name='requested-attributes'
attr-value='printer-info'
attr-value='printer-location'
