Representing application as services in Real User Monitoring semantic conventions

[ivomagi]

What are you trying to achieve?

An application in Browser RUM is defined by the user of the instrumentation library and is representing the webapp the user is interacting with. Typical values include “e-shop.example.com”, “https://bank.example.com” and “billing.internal”. In a sense the application represents the same concept that the service is designed to. But is this the case? Or should this be represented as a separate concept in semantic conventions?
