If you create a List Form web part and save it to a file or gallery you get a prompt whether you want the web part saved with a relative path (list name is stored in the web part) or fixed to thesite (list id is saved in the web part)
If you create a Data Form web part and save it to a file or gallery you do not get this prompt.
Insert > Data View > Empty Data View
Select a Data Source, then insert fields as Single Item Form.
Save Web Part to a gallery.
To make the web part generic and referencing a file name you need to do the following changes.
In the property ParameterBindings replace:
ParameterBinding Name="ListID" Location="None" DefaultValue="{01CF5B35-CB1E-4A5A-82D1-144C6A0312E2}"
with
ParameterBinding Name="ListName" Location="None" DefaultValue="Shared Documents"
Also replace
property name="ListName" type="string">{01CF5B35-CB1E-4A5A-82D1-144C6A0312E2}
with
property name="ListName" type="string">Shared Documents
remove this line
And replace each occurence of
ParameterKey="ListID" PropertyName="ParameterValues" DefaultValue="{01CF5B35-CB1E-4A5A-82D1-144C6A0312E2}" Name="ListID"
with
ParameterKey="ListName" PropertyName="ParameterValues" DefaultValue="Shared Documents" Name="ListName"
Make sure that the ListId and the List Guid do not appear any where else in the webpart.
Now you have a generic Data Form web part!
