Two similar tags: alinea and intro

What is the difference between the <alinea> and <intro> tags? My current understanding seems to make them be the same thing - variously also called a "chapeau" (Canada), an "umbrella" (Canada), "introductory text" (US House), or "top bread" (Hong Kong).

 

Also, the tag <wrap> seems to be a bit Hollywood slang'ish. Wouldn't <wrapUp> be a bit better. The other terms I have found for this is "continuation text" (US House) or "bottom bread" (Hong Kong).

 

How should a proviso be handled? I've seen cases where there is a wrap up and then if continues with a follow-on paragraph "Providing that...." That seems to be generally called a proviso and amendment language often reads "In the proviso of Section..." Should it have it's own tag?
