The comparison type. You can either choose <code>ONE_TO_ONE</code> or <code>MANY_TO_MANY</code> as the
<code>attributeMatchingModel</code>.
</p>
<p>
If you choose <code>MANY_TO_MANY</code>, the system can match attributes across the sub-types of an attribute
type. For example, if the value of the <code>Email</code> field of Profile A matches the value of the
<code>BusinessEmail</code> field of Profile B, the two profiles are matched on the <code>Email</code> attribute
type.
</p>
<p>
If you choose <code>ONE_TO_ONE</code>, the system can only match attributes if the sub-types are an exact match.
For example, for the <code>Email</code> attribute type, the system will only consider it a match if the value of
the <code>Email</code> field of Profile A matches the value of the <code>Email</code> field of Profile B.
