[Archivesspace_Users_Group] id=0 error on EAD XML import

Don't be surprised if the import fails again, with the same message but 
for a subrecord, or with a different message. That is because the 
ArchivesSpace EAD importer uses a SAX parser method 
(https://en.wikipedia.org/wiki/Simple_API_for_XML) to read the XML, not 
a DOM (Document Object Model) method. The former is faster and uses less 
memory, but cannot scan an entire XML file for issues and report back 
with a list of things to fix, as the latter would. That is why many 
people use a pre-import validation step to find most of the issues that 
might occur, without the laborious process of creating an import job, 
waiting for it to fail, then re-running.

Harvard have made theirs into a web service which you might find useful:


I think it is fairly generic (unlike a similar validation script used 
here which imposes editorial restrictions as well.)
