 Parameters cannot be used for the following constructs, as these form part of the query structure that is compiled into a query plan:
 
-* property keys; so `MATCH (n) WHERE n.$param = 'something'` is invalid
-* relationship types; so `MATCH (n)-[:$param]->(m)` is invalid
-* labels; so `MATCH (n:$param)` is invalid
+* Property keys; `MATCH (n) WHERE n.$param = 'something'` is invalid.
+* Relationship types; `MATCH (n)-[:$param]->(m)` is invalid.
+* Node labels; `MATCH (n:$param)` is invalid.
 
 Parameters may consist of letters and numbers, and any combination of these, but cannot start with a number or a currency symbol.
