Participating Org @type description incorrect

[amy-silcock]

Describe the bug Since v2, the @type description within <participating-org> has been the same as that within <reporting-org>. This is: 'The type of organisation issuing the report.'

Organisations listed as participating orgs are often not be the reporting org.

To Reproduce Steps to reproduce the behavior:

1. Go to 'http://reference.iatistandard.org/203/activity-standard/iati-activities/iati-activity/participating-org/'
2. Compare to 'http://reference.iatistandard.org/archived/105/activity-standard/iati-activities/iati-activity/participating-org/'
3. Scroll down to '@type'
4. See error

Expected behavior I suggest the wording should be changed to: The type of organisation being described.

Additional context This is a minor bug and can wait until a larger fix/upgrade is due to happen.
