problem in definition adl_relative_path.

[ghost]

I give following command, in my specialized test (excuse the camelcase)
grun Test archetypeSlot -gui

Then I give this as argument:
allow_archetype OBSERVATION[id2] occurrences matches {0..1} matches { -- Vital signs
include
domain_concept/test matches {/blood_pressure.v2/}
domain_concept matches {/.*/}
}

It gives an error:
line 4:43 no viable alternative at input 'domain_conceptmatches'

If I change the input like this:
allow_archetype OBSERVATION[id2] occurrences matches {0..1} matches { -- Vital signs
include
domain_concept/test matches {/blood_pressure.v2/}
domain_concept/test matches {/.*/}
}

I get no error.

It is because of the definition of adl_relative_path which requires a slash somewhere in the string, else it cannot make a valid argument of it. This means that a relative path, consisting of one segment can never be valid.

This will not be a big problem in real life, it will not often happen that a relativepath without slash is used, but it is a weakness of the grammar.
