HTML Purifier claims to have a robust yet permissive whitelist: this page will allow you to see precisely what HTML Purifier's internal whitelist is. You can also twiddle with the configuration settings to see how a directive influences the internal workings of the definition objects.
You can specify an array by typing in a comma-separated list of items, HTML Purifier will take care of the rest (including transformation into a real array list or a lookup table).
