Subject: zoom: attribute "ccl" optional for fieldmap
X-Git-Tag: v1.2.7~23
X-Git-Url: http://jsfdemo.indexdata.com/cgi-bin?a=commitdiff_plain;h=a99ea96b31c554425edb89e152d09ffdefc8f7ab;p=metaproxy-moved-to-github.git

zoom: attribute "ccl" optional for fieldmap

And the semantics is that no CCL field is used . The term qualifier
will be used - if defined.
