Not that I know of...

<?xml version='1.0' encoding='ASCII'?>
<block>
  <name>Test</name>
  <key>message_sink_complex_source_test</key>
  <category>Custom</category>
  <make>None</make>
  <sink>
    <name>in</name>
    <type>message</type>
    <optional>True</optional>
  </sink>
  <source>
    <name>out</name>
    <type>complex</type>
  </source>
</block>

I retried by putting the definition of <sink></sink> on top of <source></source> in the xml file, it works.

It seems that the "sink" definition must be placed on top of "source" ..

Problem solved, thank everyone !

Yes, this is the strictness of the XML DTD. Glad you got it working.
