Dear Dimitre,

used, however it sounds ugly.

Normalisation

Normalization (or 'normalisation' for those who prefer British orthography) would rather be the general process of transforming a set of values into their normalized forms. So,

<date value="2006">May Day 2006</date>
<date value="2006-05-01"/>
<date value="5-1-2006">May 1 2006</date>

might be normalized as

<date value="2006-05-01">May 1 2006</date>
<date value="2006-05-01">May 1 2006</date>
<date value="2006-05-01">May 1 2006</date>

but this would not deduplicate them.

These are very different problems, especially for XSLT. Generally speaking, deduplicating requires normalization first since deduplication works only over canonical forms (or comparing them to see which are duplicates becomes very difficult).

Cheers,
Wendell
