Common in many languages (such as PHP, the language in which WordPress itself is built), the term array is also sometimes simply called a list. It's used to refer to data that represents a collection of elements. In L&L, arrays are separated by commas without spaces. In the example below, the value of the
category attribute contains an array or a comma-separated list. Since there are no spaces and commas are not a special character in L&L, arrays within the value of attributes can be written with or without quotes around them. Attributes that accept arrays in their value are indicated in the documentation.
