Compiling dng sdk with xmp 5.1.2

I was trying to compile the dng sdk 1.3 (windows visual studio 2008), and I am hitting a snag with the XMP SDK - when compiling dng_xmp_sdk.cpp I get a:

error C2039: 'AppendProperties' : is not a member of 'TXMPUtils<tStringObj>'

Looking in the XMP notes I see that indeed AppendProperties has been decrepated in XMP SDK 5.1.2..

I assume I should be using an older version of XMP, but I cannot find it on the adobe website(s). Does anyone know where to find that ? Or am I doing something else wrong...
