I have created a class inheriting Binding called SettingsBindingExtension. The constructor takes an object of a custom type ISettingsCategory, and a string.
In my XAML, I want to be able to set the content of an element using a declaration such as

Content="{settings:SettingsBinding ISettingsCategoryObject SomeString}"

whereas, ISettingsCategoryObject is a reference to some instance of an object.

Perhaps this isn’t even possible, but if it were I don’t know what the proper syntax would be.

I’ve tried a couple ways to try and couple something like <categories:SettingsCategory> into the content assignment, but to no avail.
