The odk:tick-interval attribute on the range control element specifies the spacing between tick marks along the slider track. When present, its value MUST:
- be non-zero
- have an absolute value that is an exact multiple of
abs(step)
- be less than or equal to
abs(end - start)
If any of the conditions above are violated or the no-ticks appearance is specified, clients MUST ignore odk:tick-interval
The odk:placeholder attribute on the range control element defines the value at which the slider is displayed when the question's value is blank/null. Its value must be between start and end, inclusive, and MUST align with a step increment from start. If it is not, clients MUST ignore the value.
