And just because I'm drinking too much coffee...

If you're using an XSLT 2.0 processor for this you can do some things with
variables that might make things a little easier; e.g.

<xsl:variable name="vJournalTitle"
select="normalize-space(dcvalue[@qualifier='name'])"/>
<xsl:variable name="vJournalVol"
select="normalize-space(dcvalue[@qualifier='volume'])"/>
<xsl:variable name="vJournalIssue"
select="normalize-space(dcvalue[@qualifier='issue'])"/>

You can call those variables in a concat() function and you won't have to
deal with wonky spacing in your output. There are almost certainly a bunch
of much better ways to do this - I'll never be anything better than an XSLT
apprentice - but it might be a good starting point.

See the second <dc_identifier> for the difference in output.
Cheers.
