getting both test and graphic label for admonitions

with a simple test file, i created some admonitions and
defined the xsl:params admon.graphics and admon.graphics.extension,
and 

1) converted XML to FO with xsltproc
2) converted FO to PDF with FOP

  now, each of the admonitions has *both* a text label and a
graphic.  can i dump the text and just retain the graphic?
i thought that was the default behavior.
