For example: One record in my database is wrong and I can not obtain
datestamp information for this record. 
I could say "cannotDisseminateFormat" but in truth I can disseminate format,
I just cannot get datestamp.

What error condition do you wish to report that is not covered 
by the existing error codes? I did not find any when writing 
my server. 

My feeling is that 503 is not to be used for errors in the 
same sense as <error> replies. 503 is for cases when the
service is unavailable -- it may be used for flow control
or perhaps temporary outages such as might occur with large
updates.

Cheers,
Simeon.
