Derek Mordarski commented on XMLBEANS-403:
------------------------------------------

I have found that the class org.apache.xmlbeans.impl.common.QNameHelper also exploits \
a similar problem.

For example:
If your namespace URI is: http://www.ACORD.org/standards/PC_Surety/ACORD1.10.0/xml/

The method: public static String suggestPrefix(String namespace) will return an \
illegal prefix: x/

Your XML serialized output the ends up looking like:

<xml-fragment xmlns:x/="http://www.ACORD.org/standards/PC_Surety/ACORD1.10.0/xml/">

    <!-- Notice the illegal non-encoded forward slash used in the prefix name -->
    <x:/some-parent-node>Some text</some-parent-node>

</xml-fragment>

I have found that this is due to a bug in an algorithm within the \
QNameHelper::suggestPrefix(..) method. I have made a fix to my local version of this \
class in order to get around this bug.

If nobody is working on this bug, I'd be glad to fix it.

> Key: XMLBEANS-403
> URL: https://issues.apache.org/jira/browse/XMLBEANS-403
> Project: XMLBeans
> Issue Type: Bug
> Components: Tools
> Affects Versions: Version 2.4.1 
> Environment: Any
> Reporter: Martin Barrs
> 
> Path elements in a namespace that are considered reserved etc, are changed by the \
> code to be prefixed with an 'x'. This prefix is hardcoded in each instance it is \
>                 used - it is not event a static.
> Code: org.apache.xmlbeans.impl.common.NameUtil
> Lines: 631
> This prefix should also be configurable so that it can mesh with other generated \
> systems, i.e. Axis (see AXIS2-4269).
