+    meta.crossplane.io/readme: |
+      This composition function filters desired composed resources produced by
+      previous functions in the pipeline. Each filter matches composed resources
+      by name using a regular expression. The filter then determines whether the
+      composed resource is desired using a Common Expression Language (CEL)
+      expression.
