dictionaryWithContentsOfFile does not support <date>

I have a plist which contains elements, which I want to read by using dictionaryWithContentsOfFile.
To my surprise I noticed that the method does not support elements in the Plist.
Can this be added? Would be really helpful.

PS:

I’ve done it in my copy by adding this code in the method startElement in CCFileUtils.cpp (kind of hack, but it works):
else if(sName == “date”)
{
m_tState = SAX_STRING;
}

Because dictionaryWithContentsOfFile is used for parsing plist file generated by texturepacker or other tools.
So it may not support all types.
