|Returns the binary form of the set of octets written as a sequence of (ASCII) hex digits ([0-9A-Fa-f]).<br />{{Code|$in}} will be effectively zero-padded from the left to generate an integral number of octets, i.e. an even number of hexadecimal digits. If {{Code|$in}} is an empty string, then the result will be a {{Code|xs:base64Binary }} with no embedded data.<br/>Byte order in the result follows (per-octet) character order in the string.<br/>If the value of {{Code|$in}} is the empty sequence, the function returns an empty sequence.
