Can't use the Dependencies tag in VS2010 vsixmanifest file

Hi,

I have tried to use the Dependencies tag (For give the another VSIX file as dependency) in my custom Visual Studio Extension project vsixmanifest file under 2010 Visual Studio. But I have faced the issue like below.



Could you please suggest how can I resolve this issue?

In case if it is behavior please suggest me how can I install the multiple VSIX when install the single VSIX like this dependencies concept.?

Thanks,
