[Scilab-Dev] Unexpected implicit calls to %XMLDoc_clear()

[Samuel Gougeon]

Hello,

After defining

function  %XMLDoc_clear(doc)
     disp("hello");  // xmlDelete(doc)
endfunction

doc = xmlRead("SCIHOME/XConfiguration.xml");

yields

--> doc = xmlRead("SCIHOME/XConfiguration.xml");
   "hello"

Actually, i then get a lot of "implicit" calls to %XMLDoc_clear(). Where 
do they come from??

In the above case,

  * we in no way explicitly call clear doc;
  * we do not leave the environment where doc has been defined...

So, the usage of this feature introduced in 6.1.0 looks unclear 
(sorry...) to me.
Any clarifications?

Samuel
