Linking to subheadings

[Pbellive]

Is this possible? I know how to link to an rst file but how do I link to any heading?

ideally I could do something like

:ref:`title text <rst_file:subheading>` 

Unfortunately that doesn't work. Any ideas @lheagy @sgkang @fourndo? Searching the documentation has not helped but then again it's getting late. Perhaps the solution will emerge in the morning.

above the heading, an anchor needs to be added, eg:

.. _seismic_elastic_deformation:

Elastic Deformation
--------------------

Then, anywhere in the text, the section can be referenced as

:ref:`seismic_elastic_deformation`

which will link the text Elastic Deformation or

:ref:`Seismic Elastic Deformation <seismic_elastic_deformation>`

which will link the text Seismic Elastic Deformation
