Creation of a bidirectional link

[frisso]

When creating a link:

• use "unidirectional link" or "bidirectional link" in the link type (no "simple link")
• if the "bidirectional link" is chosen, use "Port in (direct)" and "Port in (reverse)"; use the terms "direct" and "reverse" every time we need to specify a given direction (instead of "2").
