Incorrect syntax highlighting following keywords

[jamesreprise]

Problem to Solve

This schema:

define

# attributes

#   diagram-name sub attribute,
#   value string;

#   diagram-id sub attribute,
#   value string;

# entities

    iam_secureentity sub entity, abstract;

    iam_user sub iam_secureentity,
        plays user-workspaces:has-access-to
    ;

    iam_workspace sub iam_secureentity,
        plays user-workspaces:can-access
    ;

currently renders as:

This is true for other keywords.

Current Workaround

Ignore the incorrect highlighting.

Proposed Solution

Fix the highlighting so that words that are also keywords can be used in other contexts.
