Use Robin's AttrParam taglib, it lets you specify the param name in an
attribute, or subtag. Using a subtag, something like this is possible:
<eq>
<numbers:added>
<xsp:logic>
for my $i (1..5) {
<xsp:element>
<xsp:name>num<xsp:expr>$i</xsp:expr></xsp:name>
<aprm:param><aprm:name><xsp:expr>chr(64+$i)</xsp:expr>1</aprm:name></aprm:param>
</xsp:element>
}
</xsp:logic>
</numbers:added>
</eq>
There's one drawback, however: <xsp:element> is, as far as I know, not yet
able to create namespaced elements. But a following XSLT stylesheet can
easily fix that.
If that example still looks lengthy, then wait for the next release of
axkit, we are currently devising a system that will shorten the above
example significantly.
