[MapServer-WMS Server]AccessConstrainst/Fees value not converted to lower case

[nsavard@…]

"WMS_AccessConstrainst" and "WMS_Fees" value specified within the map file are
not converted to lower case.  The value for each metadata appears within the
capabilities document as written within the map file.  The value for these
metadatas must always be "none" lower case when there are no fees or access
constraints (see below).

So a user must take care when type in the correct case for these metadatas value.

-----------------------
OGC WMS 1.1.1 specifications:

7.1.4.2. General Service Metadata

The reserved word "none" (case-insensitive) shall be used if there are no fees
or access constraints, as follows: <Fees>none</Fees>,
<AccessConstraints>none</AccessConstraints>. When constraints are imposed, no
precise syntax has been defined for the place-holder elements.

What is the problem here : the values for <Fees> and <AccessConstraints> are 
case-*insensitive* so no matter what the user enters It should work.

Marking it at won't fix. Please reopen if I missed something.
