Databind <List>?

I'm having trouble figuring out how to databind a <List> inside a
<FlowDocument>. I've tried using a <itemsControl> with a ItemsPanelTemplate
of <List>, but because List is not derived from Panel that doesn't work.

I know I could use a <ListBox>, but then the text isn't selectable along
with the rest of the FlowDocument...

Is it possible to databind a <List>?

Ok, I think I see why Document don't support databinding because of all the
intricacies involved, so what's the best current work-around if I want to
dynamically create a document from data?

My app has a databound treeview on the left, and details of the selected
node on the right. Previously I was using <TextBlock>s bound to different
properties of my objects to create the details, however I realized I need the
text to be selectable and copyable, so switched to using a
<FlowDocumentReader>, but can't get a nice generic databinding solution to
work.

The way I see it I can:

-Subclass FlowDocument for each of my classes and add DPs I can bind to.
-Subclass Paragraph, List, etc. to add DPs I can bind to, then create my
datatemplates in XAML using my new classes.
-Create a helper object that takes in one of my classes and spits out XAML.
-Subclass my classes with a ToDocument() method that returns a Document (or
raw XAML as a string).

Any suggestions on which route to proceed?

Thanks,

Ryan
