 +
 +At this time, I've only added a check to disallow "dangerous" html on fields which will display the html as is (instead of htmlEncoded like the rest of the output)
 +
 +extra requirements on the project :
 +  * el-api (v2.2 is used for tomcat6 & tomcat7, v3.0.0 is used with java8 & tomcat8)
 +  * hibernate-validator (v5.4.1.Final in case of tomcat6 & 7, use latest in case of java8 & tomcat8)
 +  * jsoup (use latest)
