NotifyWrite may be a poor implementation choice

[cnewman]

Recently, I added a NotifyWrite function that allows writing into the srcSAXEventDispatcher context. The purpose is to allow for srcML archives to be modified by policies when required.

Writing to archives is something we need to be able to do, but it is possible that doing it through the context is not the best choice (i.e., maybe we should remove it from the context). Additionally, adding a NotifyWrite function is a detriment to speed in contexts where it is not required.

In the future, we should consider whether to keep NotifyWrite and where the XML writer should be housed in order to make this as fast and maintainable as possible.
