In this file we will introduce some variations or observations on the schema that has been introduced
in this repository (You can find some screenshots in the "useful materials" folder).

1. It is still unknown if implemementing each linking text (as plain text) of a comment as an instance of the class "Linking Text"
    is better than simply relating each comment to a sequence of instances of linking text that neatly represents every 
    linking text (plain text) of the original comment. So we recommend to the potential users that wants to implement this schema
    to test both solutions in their platform (if they are interested to the performance).

2. The class "Time Primitive" is purely intended as a symbolic interface between the scope of this schema and the world of 
    mathematical and computational manipulations and the symbolic objects they define and handle.
    Therefore, the instances of "Time Primitive" must not be represented in an implementation by a universal identifier associated
    with a content model of different identity. In a concrete application, it is recommended that the primitive value system from
    a chosen implementation platform and/or data definition language be used to substitute for this class.

3. Depending on the purpose of an application, the instances of the class "old comment" can be linked to each connection of the
    instances of the class "comment" if the eventual platform is interested on keeping all relations of an old comment to the other
    elements of the schema.

4. The instances of the class "Paragraph" can also be implemented as a list of paragraphs representing those utilised by a concrete
    application if it turns out to be more intuitive or effective in the operations interested on their retrieval. The class has been showed
    in this clean form just to emphasize its central part it plays in the schema.
