Operational override for write-delay (system-property)

Question

Hi all,
I'm failing to get this xml element to validate within a cache config.
I'm using Coherence 3.7.1
<write-delay system-property="myproperty.override.write-delay" >10s</write-delay>.
the idea is to get the write-delay value atruntime through a system-property (-Dmyproperty.override.write-delay=5s for ex.)
I'm getting the following failure
Description
Location
Type
cvc-type.3.1.1: Element 'write-delay' is a simple type, so it cannot have attributes, excepting those whose namespace name is identical to 'http://www.w3.org/2001/XMLSchema-instance' and whose [local name] is one of 'type', 'nil', 'schemaLocation' or 'noNamespaceSchemaLocation'. However, the attribute, 'system-property' was found.
line 41
XML Problem
Do you know if the override is valid at that location? The documentation says YES.
What am I doing wrongly?
Thanks,
Harry

Hello Leo_TA,
thanks for the answer.
Actually I need a default value which can be overriden at runtime as described in the documentation
http://docs.oracle.com/cd/E18686_01/coh.37/e18677/appendix_cacheconfig.htm#BHCECGCF
This is very handy to move conifguration items outside the cache-config.
Do you know why the xml woul dnot validate when system-property is used in the write-delay?
<?xml version="1.0" encoding="UTF-8"?>
<cache-config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xmlns="http://xmlns.oracle.com/coherence/coherence-cache-config"
              xsi:schemaLocation="http://xmlns.oracle.com/coherence/coherence-cache-config coherence-cache-config.xsd">
</cache-config>
Coherence accepts it (when we force no xml validation (removing the xmlns)).
But I would like to use the xml validation to avoid miss-configurations.

Harry
