dots are allowed in component names, resulting in errors

[Lou]

The use of the dot '.' is allowed in Openmodelica for the name attribute. Errors could arise, since the dot is a special character.

[Adeel Asghar]

You are only allowed to add a '.' within the single quotes block. For example,

model M
 Real 'name.attribute';
end M;
