Am I limited to the InfoSets included with the Standard version?
Not at all. Anybody with a copy of Alventis Professional can create new InfoSets and share them with other users (search the User’s Guide for the description of the InfoSet Export feature). You can easily import such InfoSets into your Standard version thus extending it. If you do not want to depend on others for creating InfoSets for you, all you need is your own copy of Alventis Professional, and specifically, the Designer application that is included in it. See the Version Comparison page for more information.
