Thanks for your contribution @enricoboccadifuoco. I have a few questions regarding your PR:

1. Do you know if Falcor is used somewhere besides Netflix? I didn't hear about it previously and to be honest don't know if it's so important to add it to the roadmap. I know, it's from Netflix's developers. It looks very similar to GraphQL, but I can't find any examples of applications that use Falcor.
2. Please format XML file. You can do it for example in VS Code using XML Tools extension.

Hi,

1. I don't know if there's other big companies that uses falcor in production besides Netflix. I've found a few discussions over the web, on reddit or on falcor issues section. I'm currently using it @mosaicoon and I think it's a great alternative to GraphQL and it's a little bit less complex to set-up and use. They achieve the same results in two different ways. Here's some useful resources that talk about the main differences between these technologies:

• Jafar Husain - Falcor
• The Falcor data model is a graph, and the GraphQL data model is a tree

2. Sorry, I've formatted the xml, with 4 spaces. But I suggest you to use a .dot file to make dynamic diagrams. You could use a tool like diagrams. I think it's the easiest way to merge pull requests. If you want I can help you to refactor it.
