+## Referring to External Configuration in catalog items
+
+The same blueprint language DSL can be used within YAML catalog items. For
example:
+
+ brooklyn.catalog:
+ id: com.example.myblueprint
+ version: 1.2.3
+ brooklyn.libraries:
+ - >
+
$brooklyn:formatString("https://%s:%[email protected]/libs/myblueprint-1.2.3.jar";,
+ external("mysuppier", "username"), external("mysupplier",
"password"))
+ item:
+ type: com.example.MyBlueprint
+
+Note the `>` in the example above is used to split across multiple lines.

Much better example. I didn't realise that the `$brooklyn` prefix can be
dropped inside the scope of the function arguments; does this definitely parse?
