[OPEN-ILS-DEV] Different OSRF response format from different servers?

[Bill Erickson]

Hi Ken,

I can't say why they vary in this specific case, but it's not uncommon for
numbers to be packaged as JSON strings throughout Evergreen / OpenSRF.
Generally, Perl and JavaScript don't care and the OpenSRF JSON C library is
well-equipped to handle it.  It's probably best to assume that any number
might be delivered as a JSON number or a JSON string.
