<!DOCTYPE html>
<meta charset="utf-8">
<!--
tt-wildcard must be exactly "*". A token such as "*X" has trailing
characters after the wildcard, so it is neither a valid tt-wildcard nor a
valid tt-policy-name (the "*" is not a policy-name character). It is therefore
an invalid tt-expression and must be ignored when parsing the directive.
With no valid tt-expression in the directive value, the trusted-types list is
empty and the wildcard is not enabled (equivalent to 'none'), so
trustedTypes.createPolicy() must throw a TypeError. Both Blink and Gecko
reject "*X" as a wildcard.
