What were you trying to do that didn't work?

A customer reported that the scan result generated by oscap xccdf eval --stig-viewer <XML> ... command was not readable by STIG Viewer found on official site, a generic error "Could not parse STIG" was being returned.

I can confirm the issue, with either customer's XML or my own one generated as shown below (attached):

# oscap xccdf eval --profile cis --stig-viewer stigviewer.xml --rule xccdf_org.ssgproject.content_rule_file_permissions_var_log_audit /usr/share/xml/scap/ssg/content/ssg-rhel9-ds.xml

The XML looks sane (I tested with XML Validator), so it's unclear if STIG Viewer expects a different format or is just not aligned with generated content.
I tested on both 3.6.0 and 2.18 releases.

What is the impact of this issue to you?

Can't process XML
