#391 attribute_name attributes require specific order

[Barry Grussling]

While developing a Python script to generate mm files, I found that a tag in the attribute registry such as:
<attribute_name NAME="Foo" VISIBLE="true">

works fine, but an attribute_name tag such as:
<attribute_name VISIBLE="true" NAME="Foo">

results in a java.util.NoSuchElementException.

AFAIK, attribute tag order doesn't matter in XML. I can't tell the xml.dom module to order attribute tags, so I am post-processing the mm files so they can load into Freemind.

I am using 9 Beta 9.

Thanks,

Barry
