Change camel case parameter in reformat code in xml

hi all.
when reformat code with Alt + Ctrl + L  in hbm.xml file, changed :xxx parameter written camel case to lower case.
for sample in  "<![CDATA[ select xxx   from user u where u.oid= :userId  ]]>" if use reformat code 
“userId” convert to “userid” without developer to know create bug. if it change by default better.
Thank you jetBrains.
