PROD Page's Availability Schema is Invalid and does not represent the variant too

[steveosoule]

The PROD page's availability schema output's &mvte:product:inv_short; as the content, but most (all) customers use client-friendly inventory messages that do not adhere to the schema's expected values of: Discontinued, InStock, InStoreOnly, LimitedAvailability, OnlineOnly, OutOfStock, PreOrder, PreSale, or SoldOut.

Additionally, there are times where the l.settings:product:inv_active does not accurately reflect if the default variant's stock level. When a product has variants, it's best to use the l.settings:attributemachine:product:inv_level value.

Expected Behavior

The PROD page's meta[itemprop="availability"] tag should output valid https://schema.org/ItemAvailability values that also reflect the default variant's inventory level.

Current Behavior

Currently, it just outputs the inv_short, instead of mapping the inv_level to a valid schema value. Also, it does not account for the default variant's inventory level.

Attempted Fixes

Replace the PROD logic with something like this:

<mvt:if expr="l.settings:attributemachine:product:inv_level">
	<mvt:assign name="l.availability_inv_level" value="l.settings:attributemachine:product:inv_level" />
<mvt:else>
	<mvt:assign name="l.availability_inv_level" value="l.settings:product:inv_level" />
</mvt:if>

<mvt:if expr="l.availability_inv_level EQ 'low'">
	<meta itemprop="availability" content="LimitedAvailability" />
<mvt:elseif expr="l.availability_inv_level EQ 'out'">
	<meta itemprop="availability" content="OutOfStock" />
<mvt:else>
	<meta itemprop="availability" content="InStock" />
</mvt:if>
