Hi folks!

I've been using the key() function a lot lately, and I've been using it to 
store name tokens similar to (usually) ID values.  I would find it helpful 
if there were a way at declaration time to instruct the processor to 
tokenize the string and make individual key table entries with each 
individual token as the string value.

Also, I understand the need for the second argument of the key() function 
to be a verbatim string, but I would like a function that would tokenize 
the second argument as id() does and return all key table members with a 
value of one of the name tokens.

I am aware that a recursive function could walk through the arguments and 
tokenize them and when done act on the built-up node set ... but it is 
quite awkward.  As for the declaration, there is no way to accomplish that.

So, not to ask for the following syntax, but I would envisage something 
like the following for topic maps where attribute arguments are strings of 
multiple name tokens:

    <xsl:key name="assocs" match="assoc" use-tokenized="@types | @other"/>

       - create as many entries in table as tokens in all given strings

    <xsl:variable name="assocs" select="key-tokenized('assocs',refs/@ref)"/>

       - return as many entries from table as tokens in all given strings

Thanks!

.............. Ken
