mmweb - WebConfig.getInstance(context) - what's the context introduced with 19.1

CED Model Manager mmweb customization needs to use WebConfig.getInstance() to retrieve some info through the XML configuration file.

With 19.1 introduction WebConfig.getInstance() changed to WebConfig.getInstance(context).

Is there anybody able to explain what's the context parameter, and how to set it properly in order to re-use WebConfig.getInstance(context) to retrieve XML configuration information.
