To test this PR you need to test XML completion based on XML Schema/DTD and without it and open completion before an orphan end element.

Create a XML Schema choice.xsd like this:

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema
        xmlns:xs="http://www.w3.org/2001/XMLSchema"
        elementFormDefault="qualified"
        attributeFormDefault="unqualified">
    <xs:element name="person">
        <xs:complexType>
            <xs:choice
                    minOccurs="1"
                    maxOccurs="2">
                <xs:element name="employee"/>
                <xs:element name="member"/>
            </xs:choice>
        </xs:complexType>
    </xs:element>
</xs:schema>

create a XML file like this:

<?xml version="1.0" encoding="UTF-8" ?>
<person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="choice.xsd">
	<employee></employee>
	|</member>
</person>

open completion before member and apply it, it should generate only <member> without close it.

After write a XML file (without XSD) like this:

<?xml version="1.0" encoding="UTF-8" ?>
<person>
	<employee></employee>
	|</employee>
</person>

Here a demo:
