There are a few HTML tags and attributes which were deprecated in HTML4, but got a second life in HTML5. Among them:
i: Commonly used to make text bold or italicized,
iare redefined in HTML to have semantic meaning:
The i element represents a span of text in an alternate voice or mood, or otherwise offset from the normal prose, such as a taxonomic designation, a technical term, an idiomatic phrase from another language, a thought, a ship name, or some other prose whose typical typographic presentation is italicized.
The b element represents a span of text to be stylistically offset from the normal prose without conveying any extra importance, such as key words in a document abstract, product names in a review, or other spans of text whose typical typographic presentation is boldened.http://www.w3.org/International/questions/qa-b-and-i-tags
start=attribute for ordered lists: Indicates when a list of items should start at something other than the first item, such as when re-starting a previous list.
