I know where it is from, but question is, is it official javaee artifact?, AFAIK only with JEE7 did this became mandatory as part of JSR
for example just compare

http://repo1.maven.org/maven2/javax/javaee-api/7.0/javaee-api-7.0.pom

vs
http://repo1.maven.org/maven2/javax/javaee-api/6.0/javaee-api-6.0.pom

to see what I mean,
