In FreeMarker <authz:authorize ifAllGranted="General"> is plain static
text, so it is printed to the output as is (it isn't ignored), like
any other XML or HTML markup. JSP tags are just FreeMarker directives,
nothing special, so you use the FreeMarker directive call syntax for
calling them:

  <@authz.authorize ifAllGranted="General">...</@authz.authorize>

Note that in the FreeMarker directive call syntax you don't use ${...}
as in JSP, and don't quote the parameter values. So you do NOT write:
<@my.jspTag color="${theColor}" width="100" height=${a+b} name="aStringLiteral">
but
<@my.jspTag color=theColor width=100 height=a+b name="aStringLiteral">.
