# 622-02 : EDGAR Filer Manual v68 6.22.2

Created by: SEC Office of Structured Disclosure

## Supported Versions of XBRL Standard Taxonomies.

Refer to the SEC's public website (http://www.sec.gov/info/edgar/edgartaxonomies.shtml) for an up-to-date listing of standard taxonomy files that are supported by EDGAR, their locations, required namespaces, and where appropriate, the relevant EDGAR form types.

REMARK: There is no such section 6.22.2, it is meant to refer to 'files that are likely to be referenced but that actually we do not allow.'. Keep in mind that http://www.sec.gov/info/edgar/edgartaxonomies.xml is the ONLY authoritative source of "standard taxonomies". In this test suite we test a subset of the disallowed files, one at a time.

REMARK: Test variations that reference disallowed versions of the DEI schema may produce downstream errors as a consequence of the unloadable schema and elements in that dei namespace being undefined.
