[xep-support] Hmmm, <xref/> in figure titles

[David Nedrow]

If I us an <xref/> in the title for a figure, my list of figures shows 
not only the title of the referenced figure, but the contents of same.

Eg., in the example below, I have figure "orderedsm2lgquery" with the 
title "ORDERED FROM by smallest to largest # of rows". My second figure 
relates to the previous, so I've used an <xref/> in the second figures 
title pointing to orderedsm2lgquery as the linkend.

Unfortunately, in the output the title for the second figure as shown 
in the list of figures at the beginning of the document includes the 
entire contents of the linkend block, not just the title. If I define 
an xreflabel attribute in the first figure, the list of figures table 
is correct (though using the xreflabel rather than the title of 
course).

Is this a bug in XEP 4.2, or expected behavior (to include the entire 
block referenced rather than just the title) for lists of figures?
