Whitespace from parameters? [AVALON Frameworks issue?]
In MailetConfigImpl.getInitParameter(String name) we have:
final Configuration[] values = configuration.getChildren( name );
as best I can see, there is no call within James to trim whitespace from
around parameters, so that must be happening in Avalon Frameworks, right?
How can we stripping whitespace in the case where it would be desirable for
the admin to be able to place whitespace, e.g., in a prefix string? Is
there some attribute we could put on the tag so that Avalon Frameworks
didn't trim the whitespace, e.g.,
<subject allow-whitespace> Whitespace intact: </subject>
Other thoughts?

The code that creates a Configuration object from an XML document
(org.apache.avalon.framework.configuration.SAXConfigurationHandler) treats it
as element content. There's really no way of knowing w/o a DTD.
If there is a way to determine if an element should be treated as mixed or
element when processing the document via SAX2, that would also be a solution
in cases where a DTD was present.

Peter,
Yes, xml:space="preserve" should work, and I'll give it a whirl. The
xml:space attribute may be used to indicate explicitly that white space is
significant, which will apply to that element and any subelements that don't
reset xml:space.
However, my understanding is that white space is supposed to be significant
by default in mixed content (http://www.w3.org/TR/REC-xml#sec-mixed-content)
and insignificant in element content
(http://www.w3.org/TR/REC-xml#sec-element-content), so why isn't it being
preserved now? Is it because there is no DTD?
