Hi Philippe,
Use this (Read/write -- for write clause)

<MEMBERSECURITY >
<PERMISSION Access="Read" AllowedSet="{Descendants([Fiscal
Year].&[4])}"
UpperLevel="[Fiscal Year].&[4].Level"/>
<PERMISSION Access="Read/Write" AllowedSet="{Descendants([Fiscal
Year].&[4])}"
UpperLevel="[Fiscal Year].&[4].Level"/>
</MEMBERSECURITY>

Read: Determines which members are allowed to view. This permission
affects the size of the visible cube because it limits the members
that are displayed.
Read/write: Determines which members are allowed to be updatable. You
can define and grant this permission only if the dimension has been
write-enabled. If you grant this permission and the dimension is later
write-disabled, this permission is disabled, and end users cannot
update the dimension's members.
