In order to contribute something positive: the Motif hints are described in the Motif package, which these days is freely available, under the LGPL I believe. It contains a header file <Xm/MwmUtil.h> which contains among other things
/*

*/
typedef struct
{
/* These correspond to XmRInt resources. (VendorSE.c) */
int flags;
int functions;
int decorations;
int input_mode;
int status;
} MotifWmHints;

and a manual page VendorShell which describes the bits (as resource
values):
XmNmwmDecorations
Specifies the decoration flags (specific decorations to add or
remove
from the window manager frame) for the _MOTIF_WM_HINTS
property.
If any decoration flags are specified by the _MOTIF_WM_HINTS
property, only decorations indicated by both that property and
the MWM
clientDecoration and transientDecoration resources are
displayed.
If no decoration flags are specified by the _MOTIF_WM_HINTS
property,
decorations indicated by the MWM clientDecoration and
transientDecoration resources are displayed.
The default for the XmNmwmDecorations resource
is not to specify any decoration flags for the _MOTIF_WM_HINTS
property.
The value of this resource is the bitwise inclusive OR of one
or more
flag bits.
The possible flag bit constants, defined in the include
file Xm/MwmUtil.h, are
MWM_DECOR_ALL
All decorations except those specified by
other flag bits that are set
MWM_DECOR_BORDER
Client window border
MWM_DECOR_RESIZEH
Resize frame handles
MWM_DECOR_TITLE
Title bar
MWM_DECOR_MENU
Window menu button
MWM_DECOR_MINIMIZE
Minimize window button
MWM_DECOR_MAXIMIZE
Maximize window button
XmNmwmFunctions
Specifies the function flags (specific window manager
functions to
apply or not apply to the client window) for the
_MOTIF_WM_HINTS
property.
If any function flags are specified by the _MOTIF_WM_HINTS
property, only functions indicated by both that property and
the MWM
clientFunctions and transientFunctions resources are
applied.
If no function flags are specified by the _MOTIF_WM_HINTS
property, functions indicated by the MWM clientFunctions and
transientFunctions resources are applied.
The default for the XmNmwmFunctions resource is not to specify
any
function flags for the _MOTIF_WM_HINTS property.
The value of this resource is the bitwise inclusive OR of one
or more
flag bits.
The possible flag bit constants, defined in the include
file Xm/MwmUtil.h, are
MWM_FUNC_ALL
All functions except those specified by
other flag bits that are set
MWM_FUNC_RESIZE
f.resize
MWM_FUNC_MOVE
f.move
MWM_FUNC_MINIMIZE
f.minimize
MWM_FUNC_MAXIMIZE
f.maximize
MWM_FUNC_CLOSE
f.kill
XmNmwmInputMode
Specifies the input mode flag (application modal or system
modal input
constraints) for the _MOTIF_WM_HINTS property.
If no input mode flag is specified by the _MOTIF_WM_HINTS
property, no input constraints are applied, and input goes to
any
window.
The default for the XmNmwmInputMode resource is not to specify
any
input mode flag for the _MOTIF_WM_HINTS property.
An application that sets input constraints on a dialog usually
uses the
BulletinBoard's XmNdialogStyle resource rather than the parent
DialogShell's XmNmwmInputMode resource.
The possible values for this resource, defined in the
include file Xm/MwmUtil.h, are
MWM_INPUT_MODELESS
Input goes to any window.
MWM_INPUT_PRIMARY_APPLICATION_MODAL
Input does not
go to ancestors of this window.
MWM_INPUT_SYSTEM_MODAL
Input goes only to this window.
MWM_INPUT_FULL_APPLICATION_MODAL
Input does not go to other
windows in this application.
