Adding parameters to extensions

Throughout this book, we've run queries to register extensions in Joomla!. Within the tables where we inserted this data, there is a column named params. This column allows us to store configuration parameter values in the database. However, the column itself does not enforce any kind of format for the parameter values. To do this, we will enter the parameter values as a part of an XML document for configuration. This file will sit alongside our other extension files and contain a list of all of the possible settings.
