We'll probably want to do something more accurate in the future with a custom clang static analysis pass which validates that XPIDL interfaces have the expected vtable and struct layout, however doing so would be more involved than the string matching done in this patch. In addition to checking for extra virtual methods, we'll likely also want to check for data members on interfaces, and reject them unless the class is marked as `[builtinclass]` in addition to some other attribute which we'll need to add to prevent them from being implemented in Rust (as c++ data members will not be reflected by the rust macro). There were 2 instances of a comment which contained the word 'virtual' within a CDATA block. These comments were moved out of the CDATA block to avoid triggering the error.
