[opencms-dev] Java Expression Language EL Question

[Babak]

I am trying to understand how ${cms.element.id}is being translated in 
below source code.

https://github.com/alkacon/vie-related/blob/master/resources/detail.jsp

I mean, where at source code I should look to find the result of 
${cms.element.id}?

I know EL and I know cms is an object but in most of the codes I don't 
see any cms object
being instantiated, and it only being used in code.

Does cms object being instantiated implicitly ?
from which class and how do I find the result of <div class="box 
${cms.element.settings.boxschema}">


Thanks
Babak
