Re: [xsl] indenting maps on write

["Willem Van Lishout willemvanlishout@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

In my experience, this is hard to get right. It shows that XML attributes
weren't really conceived with the idea to write code in them.

Some ideas:
- Modify the XML parser to not do attribute normalisation (if possible in your
environment)
- Maybe try parsing the map using xsl:evaluate and reconstruct it? Although
then you will probably encounter other issues, e.g. I believe key order is
non-deterministic.
- Use <xsl:map>
- Explain your colleagues how it works and tell them to live with it.
