- indexes, you can't deduce from a set of <index> elements
- without sorting specified that the server doesn't support
- sorting -->
- <!-- MARC: which ought to be the same thing than saying that sorting is
- _not_ possible. In short, one simple <index sort="true" attribute
- should be enough to tell that sorting _is_ possible. Or we have the
- same discussion about overruling general sorting capabilities in
- specific indexes ?? Quite confusing ... -->
- <!-- MIKE: no, within an <index>, saying sort="true" means that
- you can sort on it, sort="false" means that you can't, and
- not saying anything means you're not saying anything. Three
- different cases. That's as it should be, since Explain
- records might be auto-generated by systems that can't do the
- necessary probes. So a ZeeRex record might not have "sort"
- attributes on any of its <index>es, but still say that
- sorting is supported. The client (or user) has to experiment
- to find out what indexes support it. Check the mailing list

- <!-- MIKE: No, this also applies for SRU -->
- <!-- MARC: Rrrrriiiight! That's why the section about this is called
- <schemaInfo>, and the word resultSet never appears in a SRU Explain.
- Very intuitive! -->
- <!-- MIKE: I don't understand what point you're making. SRU, like
- Z39.50, has specifications for how to do result sets. But I
- don't know whether Zebra supports them or not -->

- <!-- MIKE: it may seem natural, but it ain't what it means! -->
- <!-- MARC: but makes sense, and makes determining the list of protocol
- versions easier in a thin client -->
- <!-- MIKE: if you want to change the meaning of this, then propose
- it on-list. I doubt you'll get much support. Thin clients
- won't use this anyway, they will just speak one version and

- "Alvis Profile for SRU", assign it an opaque identifier URI,
- and point to it here. (Not today, though!) -->
