The difference is the PSGML version. It has been "fixed" in the latest 
version.

I started to rewrite the code for indentation to make it more flexible. 
There are now two (undocumented) variables to choose the strategy for 
indentation:

- sgml-content-indent-function
- sgml-attribute-indent-function

The variable value should be a function that takes an element object and 
returns the indentation to use. There are three functions included: 
sgml-indent-according-to-level, sgml-indent-according-to-stag, 
sgml-indent-according-to-stag-end.

I haven't made this "official" because there is some problems with the 
design. Attributes are usually indented with the 
sgml-attribute-indent-function, but not if the element is in mixed 
content (as in the example above) then it is indented as content. I 
think these two cases need to be separated, but perhaps there should be 
another variable instead of indenting the attributes as content. Another 
problem is that end-tags are indented as content, they should perhaps 
also be given their own variable.
