data-attributes is there a limit of length and how many?

Question

Is there a limit on html's data-attribute? Is it possible to have many data-attributes on a tag?

ex. data-a="" data-b="" data-c="" ... data-z=""

And also is there a limit how long the value on each data-attribute?

Every HTML element may have any number of custom data attributes specified, with any value.

The limit of length has been discussed in a previous question linked by Mary Melody above: Is there a limit to the length of HTML attributes?

Far of my concern. Their is no max length when defining data attribute in JavaScript just remember to always use lowercase [-variable]
