A library for creating, parsing, editing, and validating XML-based Fomod installers, widely popularized in the Bethesda modding scene

// While this hack doesn't work with enums, it does work with string literals.
// Essentially, by applying an empty constraint to the string, we can make TypeScript
// show suggestions while still allowing the string to be any string literal.
//
// Shouldn't be used in too many spots since we're pretty enum-heavy over here but it may come in handy in particular cases.
