Many management packs contains workflows that are based on the presence or lack of certain event in the event log. It is typical for these workflows to use the information contained in the event log context as the corresponding descriptions in the management pack. As a best practice, usage of event descriptions should not be hardcoded, and should use parameter references.
Using hard-coded content in your management is a bad practice of globalization. While your management pack will work on machine with an English locale, machines with a non-English locale will still show English text because it has been hard-coded. This creates customer dissatisfaction and a poor experience for non-English customers.
