[el-spec users] [jsr341-experts] Re: The new EL 3.0 String concatenation operator &, how would that work in Facelets?

Thanks for the feed back on EL 3.0.

EL has currently another xml special character, namely, <. How is this
handled in facelets?

Regardless, it seems prudent to pick another symbol for concatenation.
Consider the expression

     foo &amp;

which in EL means foo concatenate amp. Already I can see there may be
confusions. :-)

What does other EGs think about this?

I recall the other symbols we considered:

  1. ++
  2. #
  3. +=
  4. !

In any case, we should also allow the string "concat" as an operator,
like "eq" or "lt" etc.
