+ // that we need to read the main directive (i.e. <%@Page %>, <%@Control %> etc),
+ // pass it to the page parser filter if it exists, and finally read the inherits
+ // attribute of the directive to get access to the base type of the class to be
+ // generated. On that type we check whether it is decorated with the
+ // FileLevelControlBuilder attribute and, if yes, use the indicated type as the
+ // RootBuilder. This is necessary for the ASP.NET MVC views using the "generic"
+ // inherits declaration to work properly. Our current parser is not able to parse
