EXPLANATORY NOTE
The content of the document 'Constitution adopted by the Heads of State and Government, (CIG 87/2/04)' is hereby presented as a hypertextual version in order to make the highly interrelated texts easier accessible.
The Explanatory note contains two sections:
Hypertext coverage and
Screen captures with short explanations

Hypertext coverage
The hypertext covers:
The Treaty establishing a Constitution for Europe with four main parts:
Part I with 60 Articles, numbered as I-1 to I-60.
Part II with 54 Articles, numbered as II-61 to II-114.
Part III with 322 Articles,  numbered as III-115 to III-436.
Part IV with 12 Articles, numbered as IV-437 to IV-448.

In addition there are:
38 Protocols listed under A. Protocols annexed to the Treaty establishing a Constitution for Europe, and with 423 Articles in total.
50 Declarations annexed to the Final Act of the Intergovernmental Conference and the Final Act.
I have extracted the texts from these documents and revised them into smaller and interconnected segments.  The main segments are available from the Table of Contents in the left window pane. In addition, there is an expanded Table of Contents available from the upper right corner in each display. This expanded table contains 1 322 entries to all segments and Articles. The hypertext spanning over the texts from the documents listed above, are furnished with 2 008 hyperlinks in accordance with the cross- references in the original texts.

Screen captures with short explanations

Figure 1

The header section with the title 'A Constitution for Europe' is a static item and is present in all screen displays. The logo is as specified in 'Graphics handbook'.
In the upper right corner of each display, there are two links:
Front Section will lead you to the display shown in figure 1 below.
Table of Contents is an expanded version of the list shown in the left pane (see figure 5 below). It contains an ordered list of entry points to the 1 322 segments to the content extracted from the document set CIG 87/2/04 shortly presented above in the section ‘Hypertext Coverage’. If you are interested to see the text in one specific Article, it will be most convenient to locate it from this expanded content list
graphic
The table of contents in the left window pane is expandable. These entries are marked with the folder symbol and '+' (plus).  When expanded, the folder is marked with a green arrow and '-' (minus).
In figure 1, the folder Part III is expanded to show the next level; here the seven Titles of Part III, and the five Chapters of Title III.
When the cursor is placed above an entry, the entry changes colour and the whole entry text appears in a pop-up box (useful for long entries that are truncated in the left pane, and these entries are marked with suspension points [...]).
graphic
Hypertextual links in the text pane are marked as underlined in a colour different from the surrounding text (here 'state blue'). The link colour changes into ‘dark salmon’ when you place the cursor above a link. The hover colour is the same colour as the line under the blue header section.
graphic
The name of the current display is given above the light grey line in the text pane (in figure 1 the current display is 'Front Section'). Two navigation 'buttons' are placed in the right corner 'Previous' and 'Next'. At the bottom of each display, there is a button for moving to the top of a display. In addition you can apply the net browser's navigation buttons 'Back' and 'Forward'.

Because the content in these documents are divided into levels of Titles, Chapters, Sections, Subsections and Articles, I found it necessary to include 'local' content overviews. These are placed within coloured lines, and they supplement the navigational options available in the left pane and Table of Contents.
Similar lines enclose added information, e.g. information about links or explanations related to the hypertextual structure.

All cross-references between Articles or other segments are realized as hypertextual links. In the figure below, a link to the Article III-300 is activated (change of colour), which is then displayed as shown in figure 4 below.
The hypertext includes 1008 links, which indicates to what extent the Articles are interrelated. This extensive set of hypertextual links supports immediate access to referenced Articles (or Titles, Chapters, etc). In my opinion, these navigational options are quite a relief compared to following cross-references in documents prepared for print (as for instance the format PDF).
The link set is checked, but if you should enter into a detached link, you may return to the link start by using ‘Back’ in your browser. If you discover errors in the link set, please inform me by e-mail: brit.helle@aksis.uib.no.
graphic
The information given above the light grey line shows your position in the hypertext. In figure 3 below, it is shown that Article III-329 is in Chapter VIII of Title V of Part III of the Constitution. The underlined items function as hypertextual links - in this case you may for example return to Title V.

When a cross-reference to an Article is activated, the Article header is shown in the top of a display.

By using 'Back' in your browser, you will return to the link start, in this case Article III-300 shown in figure 3 above.

The screen capture below shows a subset of the 1 322 entries in the fully expanded Table of Contents.
The current selection is Section 5 in Protocol number 8. When activated, the colour turns into a darker nuance, and remains in this new colour when you return from Section 5 and until you have made a new selection.
