Seems when the target exactly matches the text within the xref element, the latter is not in the output.

<xref target="UML" format="default">UML
yields
[UML]

Expected output:
UML [UML]

Original (draft-ietf-ippm-twamp-yang-13):

   The figure is annotated
   with pointers to the UML [UML] diagrams provided...

"UML" is not in the output (all 3):

   The figure is annotated
   with pointers to the [UML] diagrams provided...

One workaround is to put more text inside the xref element, e.g.,
UML diagrams yields

   The figure is annotated
   with pointers to the UML diagrams [UML] provided ...

Or if the target is changed, even simply to lowercase, then the issue doesn't occur. (Arguably, the disappearing text is preventing unnecessary repetition, but in some cases the repetition is the desired output.)

This (suppressing identical strings) was intentional and based on legacy behaviour, I think; I'm perfectly happy to change it -- that will simplify the code and make the behaviour more predictable.

Fixed in 36a03e6:

Changed the output text for with text content equal to the reference tag to output both, rather than suppressing one. Fixes issue #571.
