<Receivers ListTemplateId="101"> specifies that the following receivers are for all lists created using the ListTemplate with Type=101, which is all the once created as pure "Document Libraries", but not "Asset Libraries", "Form Libraries", ... Custom List Templates.
If you need to cover all these then you need to either:
- specify the entire list of theses (new
<Receivers> element with all the children.
- write an event receiver for ListAdded which checks for the type of list and then adds the receivers in code if BaseType is "1" and in a FeatureReciever for your feature loop through and add them to all existing lists with BaseType="1"
