The contents of this element are usually surrounded by a CDATA
marked section, which prevents the markup-declaration-open delimiter
(<!) at the beginning of the element content from being
recognized by the parser (and thus causing an error):
<elemDecl>
<![&nil;CDATA[
<!ELEMENT list (head?, ((item*) | (label, item)+) ) >
]&nil;]></elemDecl>
The markup-declaration-open delimiter can however also be given as
an entity reference:
<elemDecl>
<!ELEMENT list (head?, ((item*) | (label, item)+) ) >
</elemDecl>
