Hi Mike,

I like this new attribute, but...

I think that the remediation info belongs locally in existing
"printer-state-message" and "printer-alert-description"
(mapped from Printer MIB remediation info), i.e., can be
found without fetching an external web page.

While the how-to-order info may be appropriate in this new
attribute, though I have seen it put in "printer-more-info"
web page.

Or was your intent that this web page was served by the
printer itself?  I think that implementation would introduce
freshness problems, i.e., distributors for resupply change
over time.

- Ira
