*Definition [#zbae55fe]
A topological space is called discretely orthocompact provided that, whenever D is a discrete family of closed subsets of X and for each F in D, U_F is an open set containing F, there exists an [[interior preserving]] open family &ref(http://www.eaflux.com/imgtex/imgtex.fcgi?%5bres=100%5d%7b$%5c%7bV_F:F%5cin%5cmathcal%7bD%7d%5c%7d$%7d%25.png); such that &ref(http://www.eaflux.com/imgtex/imgtex.fcgi?%5bres=100%5d%7b$F%5csubset%20V_F%5csubset%20U_F$%7d%25.png); for each F in D.
