    Window attribute collision detected

    Attribute: '#{@window_attribute}'
    First defined: #{@first_path}#{extract_tag_content(@first_path)}
    Conflict with: #{@conflict_path}#{extract_tag_content(@conflict_path)}

    Quick fixes:
      1. Rename one: <data window="#{suggested_alternative_name}">
      2. Enable merging: <data window="#{@window_attribute}" merge="deep">
