"<spells>" node inside magic items in official modules?

[GEONE]

Hello! I was just wondering what the purpose of the <spells> node is inside many magic items in some 5E modules. For example, potions of healing have the following node inside their entry when creating a copy of the item from a module:

        <spells>
          <id-00001>
            <name type="string">Potion of Healing</name>
            <link type="windowreference" />
          </id-00001>
          <id-00002>
            <name type="string">Potion</name>
            <link type="windowreference" />
          </id-00002>
        </spells>

Another example is Mithral Armor, with the following node in it:

        <spells>
          <id-00001>
            <name type="string">Mithral Armor</name>
            <link type="windowreference" />
          </id-00001>
          <id-00002>
            <name type="string">Chain Mail</name>
            <link type="windowreference" />
          </id-00002>
        </spells>

What is the purpose of these nodes? Do they serve some purpose or hidden feature that I'm unaware of?

Each ruleset can do things differently, please remember to indicate the ruleset you're referring to when posting in generic forums.

Sorry, I meant for the 5E ruleset

They might be left over from some sort of Item Forge building process in the past; or left over from older tools used to build modules. There is nothing in the ruleset that generates or uses that field.

Indeed, it's legacy code from Par5e.
