Declaration problem with dtd?

[MarkShark]

I get this error in my java servlet error doc when running scripts. My dtd declares "content", but I keep getting this error. I encluded the declaration in my dtd that lists "content" What could be causing this error?

ERROR:

2001-09-07 02:27:55 - path="" :Error: Element type "content" must be declared.: Error on line 5 of document

XML:
<?xml version='1.0' encoding=&quot;UTF-8&quot;?>
<!DOCTYPE course SYSTEM &quot;../DTD/sco_csf(5).dtd&quot; >

<course>
<content>


dtd:
<?xml version='1.0' encoding='UTF-8' ?>

<!--Generated by XML Authority-->

<!-- sco_csf(5).dtd -->
<!ELEMENT course (globalProperties? , block , objectives?)>

<!ELEMENT content (globalProperties?, block, objectives?)>

Shouldn't it be:
<!ELEMENT course (course)>
or
<!ELEMENT course (course+)>
?

Sorry I did typo:
<!ELEMENT course (content)>
or
<!ELEMENT course (content+)>
?
