TortoiseSVN getting user set keywords with VBA

Question

In Tortoise SVN we have set the keywords:

• "KOPF:ReviewDate" with Value "YYYY-MM-DD".

I have written a macro that reads out keywords with COM-Interface (SubWCRev) shwon here: http://tortoisesvn.net/docs/release/TortoiseSVN_de/tsvn-subwcrev-com-interface.html

I have not found a possibilty to read out the "KOPF:ReviewDate" value? Is this possible?
