// LLSimpleXUIParser is a streamlined SAX-based XUI parser that does not support localization

// Use this for reading non-localized files that only need a single param block as a result.
//
// NOTE: In order to support nested block parsing, we need callbacks for start element that
// push new blocks contexts on the mScope stack.
// NOTE: To support localization without building a DOM, we need to enforce consistent
// ordering of child elements from base file to localized diff file. Then we can use a pair
// of coroutines to perform matching of xml nodes during parsing. Not sure if the overhead
// of coroutines would offset the gain from SAX parsing
