Token is not resolved in HTML

Hi,

I have a problem with token in Semantic Fields.
Any token selected in the available list are resolved in simple text.

Ex.
1)I would like to name the class for every tags in a taxonomy field, as composed by: Field-name + Term:ID
2)I select for every items class: my-class-name-[term:tid]
3) The rendered class result in HTML: class="my-class-name-[term:tid]"

Thanks,
Bye.
