[CONNECT - CPP] Definition of TemplateSymbologyRemapperP is missing

When I include

#include <Mstn\XDataTree\MstnElementTemplate.h>

in order to use MstnElementTemplateMgr I'm prompted with following errors:

c:\programdata\Bentley\MicroStationSDK\include\Mstn\XDataTree\MstnElementTemplate.h(93) : error C2061: syntax error : identifier 'TemplateSymbologyRemapperP'
c:\programdata\Bentley\MicroStationSDK\include\Mstn\XDataTree\MstnElementTemplate.h(120) : error C2061: syntax error : identifier 'TemplateSymbologyRemapperP'
c:\programdata\Bentley\MicroStationSDK\include\Mstn\XDataTree\MstnElementTemplate.h(123) : error C2061: syntax error : identifier 'TemplateSymbologyRemapperP'
c:\programdata\Bentley\MicroStationSDK\include\Mstn\XDataTree\MstnElementTemplate.h(136) : error C2061: syntax error : identifier 'TemplateSymbologyRemapperP'
c:\programdata\Bentley\MicroStationSDK\include\Mstn\XDataTree\MstnElementTemplate.h(164) : error C2061: syntax error : identifier 'TemplateSymbologyRemapperP'

It seems to me that the definition of TemplateSymbologyRemapperP is missing.

I've looked through the header files but I've not been able to find it...

What can I do to get on with this issue ?
