Maybe. The point is that without explicit Notes, it's all too easy for an
implementor to forget XSLT even exists when implementing stuff.

The spec should say as notes:
 * When an XSLT transformation program is triggered by <?xml-stylesheet?> and
the browser implements direct-to-DOM transformation, <script> elements created
by the XSLT processor should be marked parser-inserted and should be run in the
document order (unless defer or async).

 * XSLTProcessor.transformToDocument adds <script> elements to a document that
is not in an active browsing context and, therefore, the <script> elements get
they "already started" flag set without ever getting evaluated. The scripts are
considered parser-inserted, though, so they .async property returns false in
the absence of an async attribute.

 * XSLTProcessor.transformToFragment creates scripts that aren't
parser-inserted and that don't get their "already started" flag set. Thus, the
fragment created by XSLTProcessor.transformToFragment is equivalent to a
fragment built manually by creating the elements using
document.createElementNS.
