How to create auto-bindings from property attributes?

Question

I have some data structure looking like:

public class MockObject 
{
    [ReadOnlyMember("BooleanProperty")]
    public string StringProperty { get; set; }
    public bool BooleanProperty { get; set; }
}

And a custom control which I can bind like this:

<uitest:SandboxControl Text="{Binding StringProperty}" IsReadOnly="{Binding BooleanProperty}"></uitest:SandboxControl>

I am looking for proper way to reach next behaviour:

• Control should be declared something like
  <uitest:SandboxControl BindTo="{Binding StringProperty}"></uitest:SandboxControl>
• At some point I need to get access to x:DataType declared at my root markup
• Get StringProperty PropertyInfo and extract value from ReadOnlyMemberAttribute ("BooleanProperty")
• Create code behind that extracts path from BindTo property and creates bindings
  Text="{Binding StringProperty}" IsReadOnly="{Binding BooleanProperty}"

If this approach is impossible, is there any way to get access to x:DataType value from CustomControl code? At least it opens some possibilities to create some kind of control director that will operate with text/readonly values manually.

PS: this is simplified task, because I have a bunch of attributes I have to deal with.

Any help appreciated.
