+WAP/WML templates require a php [Content-Type

+The easist way to do this would be to write a custom function that
+prints the header. If you are using [caching](#caching), that won\'t
+work so we\'ll do it using the [`{insert}`](#language.function.insert)
+tag; remember `{insert}` tags are not cached! Be sure that there is

+may fail.
