During the conversion to html I get:
jade:/home/manu/documents/manuel/TEmanual.sgml:727:18:E: document type does not allow element "INLINEMEDIAOBJECT" here; missing one of "REMARK", "SYNOPSIS", "LITERALLAYOUT", "PROGRAMLISTING", "SCREEN", "PARA", "SIMPARA", "BRIDGEHEAD" start-tag
jade:/home/manu/documents/manuel/TEmanual.sgml:735:22:E: end tag for "INLINEMEDIAOBJECT" which is not finished
What's in the sgml:
<inlinemediaobject><![ %output.print.png; [
<imageobject><imagedata fileref="&graph1001;.png" scale="40" format="png"></imageobject>
]]><![ %output.print.pdf; [
<imageobject><imagedata fileref="&graph1001;.pdf" scale="40" format="pdf"></imageobject>
]]><![ %output.print.eps; [
<imageobject><imagedata fileref="&graph1001;.eps" scale="40" format="eps"></imageobject>
]]><![ %output.print.bmp; [
<imageobject><imagedata fileref="&graph1001;.bmp" scale="40" format="bmp"></imageobject>
