action-540 check for normative language

Hi all,

David did

https://www.w3.org/International/multilingualweb/lt/track/actions/540

Today - thanks a lot for that, David.

At David: After the edits I made a few correction. I removed below 
"MUST" "MUST NOT" "SHOULD" because they are all in non normative parts: 
non-normative sections, notes, or examples.


=================
"As a general guidance, implementations of ITS 2.0 should SHOULD

"The HTML5 parsing algorithm automatically puts all HTML elements into

"The order of |provenanceRecord | elements within a |provenanceRecords | 
element should SHOULD

"The source node and the target node may be of different types, but the 
target node must MUST

be able to contain the same content as the source node (e.g., an 
attribute node cannot be the target node of a source node that is an 
element with children). "

"T he |preserveSpaceRule | element specifies that whitespace in all 
verse elements must be treated literally. elements MUST 
<http://services.w3.org/htmldiff?doc1=http%3A%2F%2Fwww.w3.org%2FInternational%2Fmultilingualweb%2Flt%2Fdrafts%2Fits20%2Fits20-before-rfc2119-check.html&doc2=http%3A%2F%2Fwww.w3.org%2FInternational%2Fmultilingualweb%2Flt%2Fdrafts%2Fits20%2Fits20.html#rfc-keywords>be

contain only Unicode characters"

Again at David: I also removed SHOULD etc. in
http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#lqissue-typevalues
Since we had an issue
https://www.w3.org/International/multilingualweb/lt/track/issues/112
to remove these.
