Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

By the way, a paper titled "An XML description of detector geometries for GEANT4" by J.Figgins, B.Walker and J.R.Comfort (NIMPR A568 (2006) 896-903) states that "Arithmetic operations can be used, with standard hierarchies regarding order, as well as many common functions (e.g., trigonometric, square-root, etc.).", and I guessed these could be used in GDML also...
