I don't know much about this topic, so this may not be the type of documents 
you're looking for. Are you aware of the following passage, on page 274 of the 
latest Unicode standard (page 19 of 
http://www.unicode.org/versions/Unicode8.0.0/ch06.pdf)? I believe that David 
Kastrup already quoted it.

I understand this as an explicit endorsement of "There’s" over "There's", and 
of l"it’s the _wrong thing_" over "it's the _wrong thing_". Mark Davis (the 
president of the Unicode consortium) clarified this in an email back in 1999:
