Here is my problem:
I wanted to use InfoPath forms, but due to complexity I have to switch to aspx forms. With Infopath Forms I could use a Forms Library, where the user is presented with
<Formname> he can click on and a nice form opens - so far so good.
I know I can have custom aspx list edit/new forms, so I could pretty much design an aspx form for a list behaving just like infoPath (the user clicking on
<formname> and a nice form opens).
The problem is that next to these "forms" or meta-data information, I also need to store Word documents in the library. No problem with a forms library: Create a document set for my form and put the form inside as well as the corresponding word document => Instant organization.
What is a way to handle metadata (a form) + documents? I can't have all form data attached to the word document as metadata, as the form itself is the leading document. Hence the title of this question: If I could put an "Item" content type within the document library, I could click on that item and attach a custom edit/new aspx form to the content type.
