What about ampersand? Is html entity code no longer necessary?

Hi, I find the less than and the greater than arrows are handy also. IE: <....>

on a doctype xhtml 1.1, better to use the unicode value, I guess

For the sake of portability, Unicode entity references should be reserved for use in documents certain to be written in the UTF-8 or UTF-16 character sets.

What user agents get numeric character references wrong in non-UTF-8/16 documents?

XHTML is a tricky beast. One school of thought is that documents should be written to be parsed by generic, non-validating XML parsers. Since they are generic they do not know HTML named character references, and since they are non-validating they don't parse the DTD to find them out either. Hence, numeric character references for everything except the XML 5.

... but if you subscribe to that school of thought, there is no point in limiting it to a specific version of XHTML. The logic either applies to all versions or none.
