Newbie: Problems with ldp.dsl

Dear friends,

I can convert sgml file with docbook.dsl but it don't work with ldp.dsl.

bash-2.05a$ openjade -t sgml  -d 
/usr/local/sgml/dsssl/docbook-dsssl-1.76/html/ldp.dsl#html test.sgml
openjade:test.sgml:3:12:E: element "ARTICLEINFO" undefined
openjade:/usr/local/sgml/dsssl/docbook-dsssl-1.76/html/ldp.dsl:355:18:E: 
reference to undefined variable "$table-width$"
openjade:/usr/local/sgml/dsssl/docbook-dsssl-1.76/html/ldp.dsl:320:28:E: 
reference to undefined variable "$verbatim-line-by-line$"

And  the path is:

bash-2.05a$ echo $SGML_CATALOG_FILES
/usr/local/sgml/dsssl/docbook-dsssl-1.76/catalog:/usr/local/openjade-1.3.2/dsssl/catalog:/usr/local/sgml/docbook/3.1/docbook.cat

Any suggestions?

Thanks in advance,
