    Also supports simple name search/lookup for both compound and member types.

    - summary for compounds generalizes title and briefdescription because
      there's no single field that works as a quick introduction for both

I collapsed all innerX tables into 'contains', which raises the prospect that
all of these very similar writeInnerX funcs could be refactored into a one,

I think the hurdles are:
- picking a first argument that every call location can pass
- which yields a consistent iterator
- accommodates PageDef's slightly different rules for generating the
  inner_refid (unless I'm missing a method that would uniformly return

/* (updated Sep 01 2018)
DoxMemberKind and DoxCompoundKind (compound.xsd) gave me some
faulty assumptions about "kind" strings, so I compiled a reference

The XML schema claims:
  DoxMemberKind: (14)
    dcop define enum event friend function interface property prototype
    service signal slot typedef variable

  DoxCompoundKind: (17)
    category class dir example exception file group interface module
    namespace page protocol service singleton struct type union

Member kind comes from MemberDef::memberTypeName()
  types.h defines 14 MemberType_*s
    _DCOP _Define _Enumeration _EnumValue _Event _Friend _Function _Interface
    _Property _Service _Signal _Slot _Typedef _Variable
      - xml doesn't include enumvalue here
        (but renders enumvalue as) a sub-node of memberdef/templateparamlist
      - xml includes 'prototype' that is unlisted here
        vestigial? commented out in docsets.cpp and perlmodgen.cpp
  MemberDef::memberTypeName() can return 15 strings:
    (sorted by MemberType to match above; quoted because whitespace...)
    "dcop" "macro definition" "enumeration" "enumvalue" "event" "friend"
    "function" "interface" "property" "service" "signal" "slot" "typedef"
    "variable"

    Above describes potential values for memberdef.kind

Compound kind is more complex. *Def::compoundTypeString()
  ClassDef kind comes from ::compoundTypeString()
    classdef.h defines 9 compound types
      Category Class Exception Interface Protocol Service Singleton Struct Union
    But ClassDef::compoundTypeString() "could" return 13 strings
      - default "unknown" shouldn't actually return
      - other 12 can vary by source language; see method for specifics
        category class enum exception interface module protocol service
        singleton struct type union

  DirDef, FileDef, GroupDef have no method to return a string
    tagfile/outputs hard-code kind to 'dir' 'file' or 'group'

  NamespaceDef kind comes from ::compoundTypeString()
    NamespaceDef::compoundTypeString() "could" return 6 strings
      - default empty ("") string
      - other 5 differ by source language
        constants library module namespace package

  PageDef also has no method to return a string
    - some locations hard-code the kind to 'page'
    - others conditionally output 'page' or 'example'

  All together, that's 23 potential strings (21 excl "" and unknown)
    "" category class constants dir enum example exception file group
    interface library module namespace package page protocol service singleton
    struct type union unknown

    Above describes potential values for compounddef.kind

For reference, there are 35 potential values of def.kind (33 excl "" and unknown):
  "" "category" "class" "constants" "dcop" "dir" "enum" "enumeration"
  "enumvalue" "event" "example" "exception" "file" "friend" "function" "group"
  "interface" "library" "macro definition" "module" "namespace" "package"
  "page" "property" "protocol" "service" "signal" "singleton" "slot" "struct"
  "type" "typedef" "union" "unknown" "variable"

This is relevant because the 'def' view generalizes memberdef and compounddef,
and two member+compound kind strings (interface and service) overlap.

I have no grasp of whether a real user docset would include one or more
member and compound using the interface or service kind.

  TODO: I wonder if this can actually be cut (just here)

  We were adding this "include" to the "includes" table alongside
  other includes (from a FileDef). However, FileDef and ClassDef are using
  "includes" nodes in very a different way:
  - With FileDef, it means the file includes another.
  - With ClassDef, it means you should include this file to use this class.

  Because of this difference, I added a column to compounddef, header_id, and
  linked it back to the appropriate file. We could just add a nullable text
  column that would hold a string equivalent to what the HTML docs include,
  but the logic for generating it is embedded in
  ClassDef::writeIncludeFiles(OutputList &ol).

  That said, at least on the handful of test sets I have, header_id == file_id,
  suggesting it could be cut and clients might be able to reconstruct it from
  other values if there's a solid heuristic for *when a class will
  have a header file*.
