MathML - Repeating Decimals

Decimal numbers having digit(s) that repeat(s) infinitely such as 1/3 (.3333...) are represented by putting a horizontal pne over or below the digits that repeat. <mstack> , <msrow>, and <mspne> elements can be used to create decimal numbers with repeated digits as shown below.
