Expression Language Keywords

The following character sequences, formed from ASCII letters, are reserved for use as keywords and cannot be used as identifiers:

				Keyword: one of
						abstractdefaultifpackagesynchronized

						booleandoimplementsprivatethis

						breakdoubleimportprotectedthrow

						byteelseinstanceofpublicthrows

						caseextendsintreturntransient

						catchfinalinterfaceshorttry

						charfinallyinterruptiblestaticuninterruptible

						constfornativesupervolatile

						continuegotonewswitchwhile

Some of these keywords, though not currently used, are reserved nevertheless.

While true and false might appear to be keywords, they are technically Boolean literals. Similarly, while null might appear to be a keyword, it is technically the null literal. And the same is true for sun, mon, tue, wed, thu, fri, sat which are technically DayOfWeek literals and neutral, male, female which are Gender literals.
