This is an XSLT issue--in your XSLT transform you have to dereference 
the entity named byh the picfile= attribute to its system ID and, as 
Nikolai says, generate src="url($system-id)". E.g:

<xsl:template match="dog">
  <fo:block>
    <fo:external-graphic src="url({unparsed-entity-uri(@picfile)})"/>
  </fo:block>
</xsl:template>

Cheers,

Eliot
