---        parent   -- Property (required)                                             
parent
    Defines a direct parent of lex class. (parent class name)

parent:dyn    
    Defines a dynamic parent of lex class. (parent class name)
    Dynamic means that parent class can be not only direct parent, 
    but parent of its parent [of parent ...] until the top class/block.

parent:file
    Defines a top schema class. (as file extensions list <*.ext1|*.ext2>)

Only one of mentioned above 'parent' properties can be used for each class.

EXAMPLE:
    parent:file = <*.c|*.cpp|*.h|*.inl|*.tli|*.tlh|*.rc|*.rc2>    
    parent        = c_CPP
    parent:dyn    = c_CPP
