The meaning of 'Change of context' in WCAG 2.0

WCAG 2.0 defines a changes in context in several ways including a change of content that changes the meaning of the Web page.

In the case of a combobox that changes the language that the page is displayed in, do you consider that a change of context is occurring? In one sense the meaning of the Web page is not changing, but to a person who does not speak the new language it is a profound change from something they understand to something they do not.

We have told a client that a Submit button is required but their developer is challenging this, claiming that the context is not changing so a button is not required.

For the purposes of this question we are ONLY interested in WCAG compliance, not usability (of course we care about usability but we are assessing whether the developer has met their contractual obligation to provide a WCAG-compliant website).

I would appreciate any insights.
