Regarding the requirement for validity checking zip relative paths in  
widget signature [1]  references, does the following change make sense  
to you?:

Change last paragraph in section 5.1, Use of XML Signature in Widgets  
to (only last sentence is changed, to two new sentences):

Every ds:Reference used within a widget signature MUST have a URI  
attribute. Every ds:Reference to an item within the widget signature  
MUST use an IDREF value for the ds:Reference URI attribute, referring  
to a unique ID within the widget signature [XML-Schema-Datatypes].  
Every ds:Reference to a widget file MUST use a  URI expressing the zip  
relative path to the widget file, properly URL encoded [URI]. The zip  
relative path MUST conform to the requirements expressed in [Widgets  

Please let me know any comment or suggestion. Thanks for noting this  

regards, Frederick

Frederick Hirsch
