Using Xcore with Xtext
The document outlines the structure and grammar of a domain-specific language (DSL) using Xtext, discussing elements like abstract elements, packages, errors in parsing, and the relationship between different models. It highlights challenges related to model generation, interdependencies of DSLs, and error handling in reference to EMF models. Additionally, it mentions the integration of Xcore and Xbase for generating models and Java APIs, emphasizing workflow configuration and necessary dependencies.
