Error message seen: There has been a problem trying to replace ${} with the XPath to the survey element named ‘’. There are multiple survey element with this name

Hello @Kal_Lam ,
Do we have a hint on this (and other reserved words) in the documentation?

We had something similar e.g. with “model”: https://community.kobotoolbox.org/t/online-validator-is-clean-but-error-message-expecting-value-line-2-column-1-char-1-seen-when-uploading-an-xlsform-in-the-server/18404/9.

Also with “start” and “end”: https://community.kobotoolbox.org/t/xml-as-requested/82/3
Kind regards
