Grammar checking has been used for a long time to validate if a given sentence - a sequence of words - complies with grammar rules. Recently attribute grammars have been proposed as a formal model to describe workflows.
A workflow specifies valid processes, which are sequences of actions. In this paper we show how a grammar checker developed for natural languages can be used to validate whether or not a given process complies with the workflow model expressed using an attribute grammar.
The checker can also suggest possible corrections of the process to become a valid process.
