bug?: XHTML serialization indentation: missing line break?

[Daniel Barclay <Da...@digitalfocus.com>]

XHTMLSerializer doesn't seem to indent right (Xerces 1.1.1).

It generates:

...
<docname>
   <one />
   <two /></docname>

I thought it would generate:

...
<docname>
   <one />
   <two />
</docname>


That is, the code doesn't seem to be generated a line break
before end tags.


Note that XMLSerializer indents as expected (for this simple XML,
at least):

<?xml version="1.0" encoding="UTF-8"?>
<docName>
   <one/>
   <two/>
</docName>

HTMLSerializer also indents symmetrically:

...
<docName>
   <one></one>
   <two></two>
</docName>

(Although one might want:

...
<docName>
   <one>
   </one>
   <two>
   </two>
</docName>

)


Here's my test program (also attached):
