Not sure how to phrase it, but my need seems to have centred on
flat to structure issues.

<mark>
 <elA>
 <elB>
 <elC>
<mark>

The plain english requirement is 'give me all the elements up to but
excluding' the next <mark>

<template match="mark">
  <wrapper>
    for-each select all up to but excluding next mark
       do something with the element
  </wrapper>
</template>

Jeni Tennisons techniques work, but I don't find it straightforward.

Any assistance for the user would help here.
