title: M2DOC : initialization of the variable self
body: <p>I would like to set the self variable to a specific PhysicalComponent in my model.
  For this, in my template wordx I set:
  m:var:self to pa::PhysicalComponent
  I imported my template in Capella 1.4.0.
  After initialize document configuration, I want to set the variable self to a specific PhysicalComponent of my model, but it doesn't work.</p>
  
  <p>With the previous version of M2DOc it was possible but with this new one (3.0.0) it doesn't work.</p>
  
  <p>Is it a bug of M2DOC ?</p>
