It's possible to implement this feature, although it would 
require compile-time XML parsing.
But I don't see big benefits from it. It's inconvenient and error 
prone. Properties of the same entity should be edited in two 
separate files, and kept in sync.

Historically, XML annotations were replaced with @ annotations in 
JPA/Hibernate once Java got support of @annotations.
Even XML files were usually generated automatically from JavaDoc 
annotations inside comments.
