The line numbers 424 and 425 are not helpful because they are in the context of the entire referenced document rather than the snippet. Also, there's no line numbering for the snippets (see earlier comment).

Note that the root identifier of the criteria reference (line 424) matches the internal identifier assigned to the CQL expression document (line 22 of Snippet 3). Also, note the use of the EXM146v4 namespace and escaped quotation marks (""") in line 425.
