According to Responsys documentation, "you can avoid such failures with the use of the exclamation point operator
(!), the double question mark operator (??), or <#attempt> and <#recover>."
However, I believe the first two methods (! and ??) would require an if-statement, and Oracle does not support nested if-statements. I would like to avoid using <#attempt> and <#recover> if I can, so I am looking for an alternative, essentially a straight forward way of doing this:
...
<#elseif conditionX>
<tr><td>Some content</td></tr>
<#if conditionY><tr><td>Some other content</td></tr></#if>
<#/if>
