\modContext_mysql
Represents a virtual site context within a modX repository.
This is the basis for the entire xPDO object model, and can also be used by a class generator {@link xPDOGenerator}, ultimately allowing custom classes to be user-defined in a web interface and framework-generated at runtime.
