Should that be {\w+[^{}]*} or something?
aside from the fact that to get a literal { in an attribute value
template you have to use {{ You probably want to allow any number of {}
groups inside your word so that would be
(\w|{[^{}]*})+
ie a sequence of one-or-more (word character or brace-group)
written as
regex="(\w|{{[^{{}}]*}})+"
