Re: [xsl] How to implement a sequence of sequences?

[Dimitre Novatchev <dnovatchev@xxxxxxxxx>]

List of lists has been used in FXSL since 2001.

Of course, this has nothing to do with sequences:

<list>
 <el1/>
 <el2/>
 <sublist1>
  <el11/>
 <el12/>
 </sublist1>
</list>

One can wait for XPath 3.0 or implement an extension object that is a
single item in a sequence but has a method to provide the internal
(sub) sequence it keeps inside itself.

Of course, it is most probable that most or all (none) of the standard
functions on sequences will work directly with those two options.
