Assuming a parent math element, I think that's allowed but will have a
default rendering as if the reln elements are contained in an mrow. If you
are concerned about the presentation (but don't want to use parallel
markup), then you might prefer to enclose them in an mtable. But the
obvious content markup here is simply:

<apply>
  <and/>
  <reln>...</reln>
  <reln>...</reln>
</apply>
