+description: |-
+    This profile contains all the rules that once belonged to the
+    ubuntu2204 product via 'prodtype'. This profile won't
+    be rendered into an XCCDF Profile entity, nor it will select any
+    of these rules by default. The only purpose of this profile
+    is to keep a rule in the product's XCCDF Benchmark.
