2.1.1153 Part 1 Section 19.5.31, cond (Condition)

a.   The standard does not state a default value for the delay attribute.

PowerPoint uses a default value of 0 for the delay attribute.

b.   The standard places no restrictions on the relationship between the value of the evt attribute and the child elements of the cond element.

PowerPoint does not support the rtn, tgtEl, or tn child elements when the value of the evt attribute is none; if the evt attribute has any other value, the child element specifies the target of the event.
