Matching begin and end tags #43
Description
Describe the need of your request
At the moment the begin and end tags have no requirement by the lexer to match. In order to prevent mistakes by the user to miss a matching end or begin tag this needs to be fixed.
Proposed solution
Change the bnf and flex files to make the begin and end tags matching.
Alternatives you've considered

Additional context
There is complexity here as the language is injected and the matches need to be able to resolve in an injected context.
