<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">The hypothesis for this behaviour is that, for a template attribute, when using a dependency that is another attribute and not a connector, the names of the source attributes play no role. Whatever source attribute name is asked from an attribute resolver, the attribute resolver always returns its value no matter what. So the sourceattribute tags have no bearing, save for their number. That makes problematic any situation where the values of two or more attributes must be combined using a template. </p>
