Version 4.6.2

4.6.2 (2018-09-06)

Refactor AttributeValueBase::set_text method.

• set_text is doing too many things. At least the structure is a bit cleaner;
  though, still complex.
• set_text will set the type if no type has been set.
• set_text should not modify the type if it has already been set,
• set_text should not depend on the type's namespace.
• set_text should not interfere with the 'anyType' type.
• set_text will raise a ValueError if the value cannot be represented by the
  type.
• set_text will raise a ValueError if the type is unknown.
