I agree with this approach - define a "TextBox" entity with
whatever properties you want (including its size / position on your
"layout") in your model, then you can store / retrieve this
"description" of a text box. You can recreate the NSTextField or
NSTextView when the document is loaded (or whenever) based on the
parameters if the TextBox instance or store its new parameters in the
database when they change.
You may want to read the Core Data Programming Guide to get a
better understanding of these concepts. Also reading up on an intro
to relational databases would be a great help as it seems you're
having trouble conceptualizing the abstraction of objects as
"entities" (not that I'm an expert myself, but my DBA skills have
definitely helped me understand Core Data and use it well from the
very beginning).
The bottom line is that you certainly *can* "represent" a text
field in a core data (or any) database/store, just like you can
represent pretty much *anything*, but you just can't "store a text
field in the database" directly, so to speak, especially not by
inserting your own home-brewed XML into a stock Core Data store.
Hope this helps.

I guess that what you want for that is not a "textbox" in a core
data document but an entity in the object model that represents a
textbox. That entity will have a property named maxinput of type
integer and another property "name" of type String.
Hope this helps.
