Subject: [PATCH] Write standard levels as level elements in XML

Standard.getLevels had no XML wrapper annotations, so the XML generator
wrote each level as a <levels> element inside <levels>. The XSD expects
<levels><level>, so re-generating the spec test file
valid-standard-1.6.xml (or the JSON one) gave an invalid BOM.

Annotate it like getRequirements and Level.getRequirements.
