Allow custom attributes to specified on externals in process definitions.

<process-definition name="Graph I">
  <node name="A"/>
</process-definition>

<process-definition name="Graph II">

  <node name="B">
    <arc external="G1" to="A"/>
  </node>

  <external name="G1" processDefinition="Graph I">
    <custom>
       <foo>bar</foo>
       <hello>world</hello>
    </custom>
  </external>

</process-definition>

<process-definition name="Graph III">

  <node name="C">
    <arc external="G2" to="B"/>
  </node>

  <external name="G2" processDefinition="Graph II">
    <custom>
      <foo>baz</foo>
    </custom>
  </external>

</process-definition>
If you get node A from graph III, you can observe the following:
 Node nodeA = ...;
 nodeA.getExternalEnv().getAttribute( "foo" ) // returns "baz"
 nodeA.getExternalEnv().getAttribute( "hello" ) // returns "world"
 nodeA.getExternal().getEnv().getAttribute( "foo" ) // returns "baz"
 nodeA.getExternal().getEnv().getAttribute( "hello" ) // returns null
 nodeA.getOriginatingExternalNode().getExternal().getEnv().getAttribute(
"foo" ) // returns "bar"
 nodeA.getOriginatingExternalNode().getExternal().getEnv().getAttribute(
"hello" ) // returns "world"
