Added 29119 resolution (xs:error) to internal drafts

I added the resolution of 29119 (xs:error) to our internal drafts:

https://www.w3.org/XML/Group/qtspecs/specifications/xquery-31/html/xquery-31.html#id-xs-error

I'm not sure that this last bullet point is correct:


  *   declare function f($arg as xs:error) {...}; is a valid function declaration, but it always raises a type error<https://www.w3.org/XML/Group/qtspecs/specifications/xquery-31/html/xquery-31.html#dt-type-error> [err:XPTY0004<https://www.w3.org/XML/Group/qtspecs/specifications/xquery-31/html/xquery-31.html#ERRXPTY0004>] or a dynamic error<https://www.w3.org/XML/Group/qtspecs/specifications/xquery-31/html/xquery-31.html#dt-dynamic-error> [err:XPDY0050<https://www.w3.org/XML/Group/qtspecs/specifications/xquery-31/html/xquery-31.html#ERRXPDY0050>] if the function is called.

Thoughts?
