<!ELEMENT META - - (%text;)*>
    <!ATTLIST META
	    HTTP-EQUIV  NAME    #IMPLIED
	    NAME        NAME    #IMPLIED
	    SCHEME	NAME    #IMPLIED	>
I think we would not want %text to be the content model in any case
(since that would give folks the wrong idea that this was displayable
content); more preferable would be one of the following:
    <!ELEMENT META - - CDATA>
    <!ELEMENT META - - (#PCDATA)*>
Also, whatever attribute name you choose for SCHEME, it should
have a declared value of NOTATION, not NAME.
