how to pass composite object to view model

I'm using mvvm light with wpf.

Currently i can pass string parameter to viewmodel's command like below: 

<TextBox Height="23" TextWrapping="Wrap" Text="TextBox" Name="textbox1"/>
<Button Command="{Binding ShowMessage}" Content="Click Me"
        CommandParameter="{Binding ElementName=textbox1, Path=Text}" />

My question is how to pass composite type like Person to a command of ViewModel?

Thanks

<TextBox Height="23" TextWrapping="Wrap" Text="TextBox" Name="textbox1" Tag="{Binding Person}"/>
<Button Command="{Binding ShowMessage}" Content="Click Me"
CommandParameter="{Binding ElementName=textbox1, Path=Tag}" />

you can make use of Tag Property of TextBox but I think there is something wrong with your MVVM implementation,It is the ViewModel that holds the data for your view. But here you sending it from View to VM . I mean Person should be automatically there in your VM instead of sending it from View.
