The XML elements for subfunctions for variables and values (see section 9.7.1 on page ) have the names:

• value: value
• variable: variable

They contain a number each. Where the variable subfunction (variable) contains the value of the number / identifier of the variable, as it is defined above.

Furthermore, there are real subfunctions (see section 9.7.2 on page ). These contain for each of ther subfunction a XML element.

Names of subfunctions with an arity of one are:

• abs: absolute value
• sin: sine
• arcsin: arc sine
• log: logarithm
• round: round
• delay: delay

Names of subfunctions with an arity of two are:

• add: addition
• sub: subtraction
• mult: multiplication
• div: division
• mod: modulo
• exp: exponent
• min: minimum
• max: maximum

In the sub, div and exp subfunctions the the sequence of the contained XML elements is important. In them the first contained XML element is the first contained subfunction of the subfunction.

Other subfunctions:

• if: if-function (before its two subfunctions, first the condition of the if-subfunction is stored, the order of the XML subelements is: condition, true case (subfunction), false case (subfunction); see section 22.3.8 on page )
