XForms CR - 7.6, 7.7, 7.8 Methods/Functions?

In the headings for 7.6 to 7.8 the term "Methods" is used in the main section 
header but "Function(s)" is used in the subheadings and text.

A corresponding variation in terms occurs in the contents section of the CR.

Was it intended that "Function(s)" be used consistently?
