Error 8000000a "The data necessary to complete ..."

I´m using this DOCTYPE:

<!DOCTYPE xsl:stylesheet [
    <!ENTITY % HTMLlat1 PUBLIC "-//W3C//ENTITIES Latin 1 for XHTML//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml-lat1.ent";>
    %HTMLlat1;
]>

and I´m getting this error:

msxml4.dll error '8000000a'

The data necessary to complete this operation is not yet available.

Anybody knows what´s that? pleaseeeeeeeee

(Yes, David. It´s not working yet)
