Thank you for your comments Adam. Your suggestion solves the issue with
yaz-client. But how might one bring about the same result with PHP/YAZ
(v. 1.0.12)? Is there a -- undocumented? -- way to pre-init SUDOC
(removing namedResultSets negotiationModel) possibly using a
`yaz_connect' or `yaz_set_option' option? I have searched the YAZ
3.0.10 release notes without finding any pointers.


Kind regards,

 Richard
