For TJSJ/SJU; the [Briefing Page] states under departures (Note 3) that taxiway restrictions and taxiway holding position information are located on the [Parking Gate Chart].  Similarly; the [Airport Diagram] shows an area on the west side of the airport bounded by a thin dashed line with a note stating; 'For Taxiway Restrictions See [the Parking Gate Chart].'However; the most current [Parking Gate Chart]; as found in the EFB and also on the company intranet has nothing of the sort.  It is only a list parking gate coordinates and a diagram showing their location on the terminal.  No information on this page describes any taxiway restrictions; and no information on the diagram or the text depicts any taxiway holding positions. The 'changes' information at the bottom of the current [Parking Gate Chart] states; 'Changes: Parking gates; chart reindexed.'  Perhaps in the re-indexing process this chart became the [Parking Gate Chart]; without any corresponding update to the notes on the [Airport Diagram] and the [Briefing Page].  Since no other chart in the current section on SJU appears to contain the missing information; it seems possible that the relevant chart has been omitted entirely. To the extent that Aircrews operating into SJU; particularly for the first time; need to be aware of the 'restrictions' contained on the now-missing page; this omission compromises the Safety of operations at SJU.
Air carrier pilot reports that the Airport Diagram for SJU has a note on the left side of the chart indicating that taxiway restrictions for this area can be found on the Gate Diagram; but there is nothing there.
