Prevent x005F from xml

When I run this query:
SELECT
xmlelement(name my_xslt_tag,
(SELECT XMLPARSE (CONTENT '<![CDATA[<foo>bar</foo><bar>foo</bar>]]>'))
)

I get this result:
"<my_x005F_xslt_tag><![CDATA[<foo>bar</foo><bar>foo</bar>]]></my_x005F_xslt_tag>"

Running soemthing similar in mssql prevents the x005F
SELECT 'data' AS p,'data' AS k
FOR XML RAW('xmlst')

How do I prevent the x005F in the tagname without changing the tagname?

Best,
