This issue adds the <strong>"other" option variants</strong> (<code>select_other</code>, <code>radios_other</code>, <code>checkboxes_other</code>, <code>buttons_other</code>) and fixes <strong>multiple-value / custom-composite</strong> handling, both for querying and for submission.</p> <p>Gaps in 3.x:</p> <ul> <li>"Other" elements are not supported: the free-text "other" option, its label (<code>#other__option_label</code>) and its placement in the option list are not exposed, and submissions that use the "other" value are not accepted/validated.</li> <li>A composite element containing an "other" sub-element cannot be submitted.</li> <li>An element's <code>description</code> is dropped when the element is configured as <code>#multiple</code>.</li> <li><code>multipleValues</code> is resolved incorrectly for custom composite elements.</li> </ul> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <ul> <li>Support the "other" element family: add a <code>webform_element_other</code> data producer that resolves the other-option label and value, and expose them on the relevant element types.

Element descriptions and <code>multipleValues</code> are now resolved correctly for multiple-value and custom-composite elements.</p>
