Re: inline-graphic

I am using
<fo:block>
<fo:inline-graphic href="file:logoitau.gif"/>
</fo:block>
to insert an illustration in my pdf, but not this
working, the cocoon accuses the following error:
"Unknown formatting object
http://www.w3.org/1999/XSL/Format^inline-graphic".
What should make?, thank you.
