I'm trying to build a CRUD module for Magento 2 by using the ui components.
but I need to add a prefix for all my inputs in the form.
So if I add a field called name I need the field name to actually be prefix[name].
Using the Magento\Framework\Data\Form class to generate my fields worked great with

$form = $this->_formFactory->create();
$form->setHtmlIdPrefix('prefix_');
$form->setFieldNameSuffix('prefix');

But I want to do it via ui component xml.
Here is how my xml looks right now:

<?xml version="1.0" encoding="UTF-8"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">

                    <item name="formElement" xsi:type="string">input</item>
                    <item name="source" xsi:type="string">[entity]</item>
                    <item name="sortOrder" xsi:type="number">10</item>
                    <item name="dataScope" xsi:type="string">name</item>
                    <item name="validation" xsi:type="array">
                        <item name="required-entry" xsi:type="boolean">true</item>
                    </item>
                </item>
            </argument>
        </field>
    </fieldset>
</form>

This works nicely, and generates the add/edit form with a single field called name but I don't know how to add the prefix.
