[jboss-as7-dev] Changing AttributeDefinition default for allowExpressions

[Tomaz Cerar]

Hi,

Given lots of input from different channels it would make sense to change default for all AttributeDefintions to have allowExpresions set to true.
That would come into play for all code that uses AttributeDefintion but would not apply to those subsystems not yet converted AS7-4788

It would still make be possible to disable support for expressions if you explicitly do not want them.

But please note that even if we do change default to true, it would still not work for all use cases as many subsystems still do not properly parse xml / read model to actually benefit from this 
but it would still solve many issues when all rules are obeyed but attribute was not marked to support expressions.

wdyt?
