    <!-- institution. This selects the individual name element if it is coded as 'resourceProvider'. AGSL is using that element to specifiy the institution, though it's probably more properly used for an individual creating the metadata. This definition needs to be more generalized and codified. OGM Aardvark recommends a controlled list for this based on the institutions that are using GeoBlacklight so they can be associated with logos. Since we don't have that, we'll just go with what we've got.  -->
