[XML-SIG] Useless fun thing for XML - comments or helpers?

Note that nodes can contain other nodes (bookmarks and nodes are 
mixed in the order they are found), and the top node doesn't have
a name element.  Let's see...  Is the following valid syntax?

    <!ELEMENT NODE     (NAME?, (BOOKMARK|NODE)+)>

I'm not that happy about the name "node" either...  anyone have a
better idea?

...

And yes, MSIE also uses a timestamp for each bookmark:

[InternetShortcut]
URL=http://www.secretlabs.com/
Modified=107CD6B43F8ABD019D

(haven't figured out how to decipher that one yet)

Netscape uses at least three: ADD_DATE, LAST_VISIT, and
LAST_MODIFIED (standard time_t's).

How about:

<!ELEMENT BOOKMARK (NAME, URL, ADDED?, VISITED?, MODIFIED?)>

(where dates are stored according to http://www.w3.org/TR/NOTE-datetime
or RFC1766 or something -- is there a "defacto standard" for dates in XML?)
