No.

In your first example the attribute has a single value, "1|2". You can
interpret that value any way you like. If you want the value of the
attribute to be a list then it's more common (and supported by XML
Schema) to use a space as the separator.

Holding data redundantly is a bad idea. A much better solution is to
switch from using attributes to using child elements.

I can't quite see what this has to do with XSLT?
