Converts a sequence of octets to a base64Binary value.
octets-to-base64Binary($octets as xs:integer*) ➔ xs:base64Binary
The sequence of octets
Notes on the Saxon implementation
Available since Saxon 8.1.
This function takes a sequence of integers as input, and treats them as octets. The
integers must therefore all be in the range 0-255. The result of the function is the
xs:base62Binary value representing this sequence of octets.
