C# WPF IsEnabled using multiple bindings?

Question

I have a WPF xaml file describing a section of a GUI and I'd like the enabling/disabling of a particular control to be dependent on two others. The code looks something like this at the moment:

<ComboBox Name="MyComboBox"
          IsEnabled="{Binding ElementName=SomeCheckBox, Path=IsChecked}"/>

But I'd like it to be dependant on another checkbox as well so something like:

<ComboBox Name="MyComboBox"
          IsEnabled="{Binding ElementName=SomeCheckBox&AnotherCheckbox, Path=IsChecked}"/>

What's the best way to go about that? I can't help feeling I'm missing something obvious or going about this the wrong way?

I believe you may have to use a MultiBinding with a MultiValueConverter. See here: http://www.developingfor.net/wpf/multibinding-in-wpf.html
