  Put tag can have following atributes :

  - name : Name of the attribute
  - value : value to put as attribute
  - type : value type. Possible type are : string (value is used as direct string), template (value is used as a page url to insert), definition (value is used as a definition name to insert), object (value is used as it is)
  - role : Role to check when 'insertAttribute' will be called.

  Value can also come from tag body. Tag body is taken into account only if value is not set by one of the tag attributes. In this case Attribute type is "string", unless tag body define another type.
