Doesn't it depends on the gml application schema whether property
content may be by reference. If you follow the pattern used in ISO19139
(section 8.4), object references may be used in property elements
<property xlink:href="#1gmlID_pointer"> where the href can be any URI. I
believe this is gml compliant. We use this extensively in GeoSciML.
