dtd-parsing

Hi,

Using the DTD validator here, I am informed that the following DTD is invalid.

<!ENTITY % text "(#PCDATA|L)*">
<!ELEMENT H         (%text;)+>
<!ELEMENT L         (#PCDATA)>

The error message is: "A '(' character or an element type is required within declaration of element type "H"." at line 2, column 22.

Can anyone please point out why it is invalid? The error message is not exactly very friendly to me. Thanks.
