Hi all again,

looking into the "confidence score" attributes again, I saw these three 
paragraphs:

" Any node selected by the MT Confidence 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#mtconfidence> 
data category MUST 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#rfc2119> 
be contained in an element with the |toolsRef| (or in HTML5, 
|its-tools-ref|) attribute specified for the MT Confidence 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#mtconfidence> 
data category. For more information, see Section 5.8: ITS Tools 
Annotation 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#its-tool-annotation>."

" Any node selected by the terminology data category with the 
|termConfidence| attribute specified MUST 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#rfc2119> 
be contained in an element with the |toolsRef| (or in HTML5 
|its-tools-ref|) attribute specified for the Terminology 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#terminology> 
data category. See Section 5.8: ITS Tools Annotation 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#its-tool-annotation> 
for more information."

" Any node selected by the disambiguation 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#Disambiguation> 
data category with the |disambigConfidence| attribute specified MUST 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#rfc2119> 
be contained in an element with the |toolsRef| (or in HTML5 
|its-tools-ref|) attribute specified for the disambiguation 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#Disambiguation> 
data category. For more information, see Section 5.8: ITS Tools 
Annotation 
<http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#its-tool-annotation>."

However, the examples for  termConfidence (ex. 40) and 
disambigConfidence (ex. 54) show no toolsRef (or its-tools-ref) 
attribute. Are the examples wrong or is toolsRef / its-tools-ref 
optional for termConfidence and disambigConfidence?

Thanks,

Felix
