+In the above example v_plus and v_minus are never prefixed with "slot/" because
+of their noslot attribute. In case the symnbol is used with the slot attribute
+set, this means:
+<ul>
+	<li> "in_plus", "in_minus" and "out" will be copied/duplicated for each slot
+	     (e.g. as "A/in_plus" for slot "A") for the abstract component
+	<li> v_plus and v_minus are kept common and only one copy of them will
+	     exist in the abstract component
+</ul>

+<p>{des7:0}
+Note: when the same symbol is used in a non-slotted use case, the symbol will
+not have the "slot" attribute; in this case no terminal name translation
+applied and the resulting abstract component will have the same port names
+as the terminal names of the symbol.
