+ 
+== Overview ==
+
+This RFC is for adding an additional syntax to the concat function of the expression engine.
+
+== Motivation ==
+
+The existing concat function syntax is difficult to work with when multiple concatenations need to be done. It requires the concat functions be nested whenever a new item needs to be concatenated.
+
+== Proposed Solution ==
+
+The proposed solution is to add support for an additional syntax to the concat function.
+
+Old syntax:
+{{{
+concat('Parcel ID: ', concat( PID , concat('\nOwner Name: ', concat( OWNER_NAME , concat('\nAddress: ',  SITE_ADDR )))))
+
+}}}
+
+New syntax:
+{{{
+concat('Parcel ID: ', PID , '\nOwner Name: ', OWNER_NAME, '\nAddress: ', SITE_ADDR )
+
+}}}
+
+The new syntax will consist of a comma delimited list of concatenation items.
+
+== Implications ==
+
+The existing concat function syntax will continue to be supported in addition to the new syntax.
+
+== Test Plan ==
+
+Test that the existing and new concat function syntax work.
+
+== Funding/Resources ==
+
+None at this time.
