 Accordingly, the following identifiers are all valid,
 
 
-    ``mynode1``, \qquad ``_SolarPlant_2``, \qquad ``HydroStorage_a``.
+    ``mynode1``,  ``_SolarPlant_2``,  ``HydroStorage_a``.
 
 Besides these lexical requirements, identifiers must also be unique in their respective scope. Hence, no two nodes may have the same identifier since this would prohibit the unambiguous identification of a particular node.
 Similarly, variables and parameters may not have the same identifier as a node or other variables and parameters belonging to the same node.
