==What is the "Special - XML" Custom field and why would I use it?==

XML (Extensible Markup Language) is a type of custom field used to create budgets and lists of information. This advanced custom field opens in a modal window, it can have multiple sections, and it is robustly configurable (formulas, validation, reporting). If you are looking to create a basic lists or budget, you can also use the field called '''Special - In-Line Data Grid.'''
