officecfg/registry/schema/org/openoffice/Office/Chart.xcs used hex numbers
(starting with "0x") in a value of type oor:long-list, which appears to be an
undocumented feature of the old configmgr implementation.  (oor:long-list is
based on xs:long, which only supports decimal numbers, see
<http://www.w3.org/TR/2004/REC-xmlschema-2-20041028/#long-lexical-representation>.
 Consequently, the new configmgr implementation also only supports decimal numbers.)

Fixed as <http://hg.services.openoffice.org/cws/sb111/rev/62944ee586b0>.

->sb, what will happen if the user migrates his settings from an older version
where the data is provided in hex form still?

@iha:  The hex values only appeared in
<basis>/share/registry/org/openoffice/Office/Chart.xcs, which is not migrated
(it is replaced by <basis>/share/registry/main.xcd during an updated).  If the
user made additional settings of those color values through the OOo UI, those
would have been written to the UserInstallation registry data by the old
configmgr as decimal values; migration of UserInstallation registry data will
thus handle them correctly.  Only if the user made additional settings of those
color values by manually editing UserInstallation registry data files---and used
hex notation when doing so---would a problem arise.

@sb, that is good news. Thanks! :-)

(Due to issue 107578, hex notation is now supported for backward compatibility
by new configmgr, anyway.)
