Narrative:

When crosschecking the [line selected] txmex RNAV STAR into houston; I discovered that the 280 and 210 hard speeds at txmex and crvza; respectively; were not displayed. I contacted the dispatcher to see if he knew why? He returned an ACARS message advising the flight planning software team said the program only does mach speeds; knots can't be entered.in any case the commercial producers of the database need to be informed so they can include the missing speeds in the next revision.
