Provide more reliable location of errors
File names and line number information was not reliable available when producing error messages. Some items have embedded line number information, and sometimes the S#state.type and/or S#state.value could be used to retrieve the line number information. To make sure that we can always retrieve at least an approximate error location, store the top-level construct being checked in S#state.error_context. Example of top-level constructs: Seq ::= SEQUENCE {...} i INTEGER ::= 42 This is a short-term solution. In the long term, we would want the parser to include line number information in all items.
