OCCT 6.3.0 Doxygen documentation is broken for Graphic3d package

As reported by prospect, OCCT 6.3.0 Doxygen documentation is broken for
Graphic3d package: the links on relevant page do not lead to correct classes.

Look here:
 
http://sbu.nnov.opencascade.com/maintenance/doc/releases/OpenCASCADE6.3.0/doc/
ReferenceDocumentation/Visualization/html/packages/Graphic3d.html

For instance, clicking on class Graphic3d_Strips leads to page describing class
Graphic3d_Texture1D...

This seems to be a problem of documentation generator, so similar problems may
be expected in other parts of documentation too
