[v3.0] Issue with validating InternationalAIN

[MichaelJRussell]

I found an issue with our handling of the new support for international AINs, and while testing that, I found that all CVIs using the InternationalAIN element are being flagged as invalid. The issue seems to be with this block defining the allowed tag elements, it's missing the InternationalAIN option, so no CVIs with that element will be considered valid:

eCVI/ecvi2.xsd

Lines 1039 to 1049 in 6684182

	<xs:choice>
	<xs:element ref="AIN"/>
	<xs:element ref="MfrRFID"/>
	<xs:element ref="NUES9"/>
	<xs:element ref="NUES8"/>
	<xs:element ref="OtherOfficialID"/>
	<xs:element ref="ManagementID"/>
	<xs:element ref="BrandImage"/>
	<xs:element ref="EquineDescription"/>
	<xs:element ref="EquinePhotographs"/>
	</xs:choice>

Am I missing something? This seems like a major blocker to implementing v3 unless/until that gets resolved.

Edit: I generated an example CVI using fake data to demonstrate the issue: https://gist.github.com/MichaelJRussell/0ebd2c8227c9dbd358b756312be4972b

I'm unclear on what the process is for making changes to the standard for fixing issues outside of the normal release cadence, but I went ahead and opened up a pull request for discussion / consideration to implement the change needed to use InternationalAIN as a valid animal tag: #92
