//Flags
//The following axis value table flags are defined:
//Mask Name Description
//0x0001 OLDER_SIBLING_FONT_ATTRIBUTE If set, this axis value table provides axis value information that is applicable to other fonts within the same font family.This is used if the other fonts were released earlier and did not include information about values for some axis. If newer versions of the other fonts include the information themselves and are present, then this record is ignored.
//0x0002 ELIDABLE_AXIS_VALUE_NAME If set, it indicates that the axis value represents the “normal” value for the axis and may be omitted when composing name strings.
//0xFFFC Reserved Reserved for future use — set to zero.
//When the OlderSiblingFontAttribute flag is used, implementations may use the information provided to determine behaviour associated with a different font in the same family.
//If a previously - released family is extended with fonts for style variations from a new axis of design variation,
//then all of them should include a OlderSiblingFontAttribute table for the “normal” value of earlier fonts.
//The values in the different fonts should match; if they do not, application behavior may be unpredictable.
// Note: When the OlderSiblingFontAttribute flag is set, that axis value table is intended to provide default information about other fonts in the same family,
//but not about the font in which that axis value table is contained.
//The font should contain different axis value tables that do not use this flag to make declarations about itself.
//The ElidableAxisValueName flag can be used to designate a “normal” value for an axis that should not normally appear in a face name.
//For example, the designer may prefer that face names not include “Normal” width or “Regular” weight.
//If this flag is set, applications are permitted to omit these descriptors from face names, though they may also include them in certain scenarios.
//Note: Fonts should provide axis value tables for “normal” axis values even if they should not normally be reflected in face names.
//Note: If a font or a variable-font instance is selected for which all axis values have the ElidableAxisValueName flag set,
//then applications may keep the name for the weight axis, if present, to use as a constructed subfamily name, with names for all other axis values omitted.
//When the OlderSiblingFontAttribute flag is set, this will typically be providing information regarding the “normal” value on some newly-introduced axis.
//In this case, the ElidableAxisValueName flag may also be set, as desired.When applied to the earlier fonts,
//those likely would not have included any descriptors for the new axis, and so the effects of the ElidableAxisValueName flag are implicitly assumed.
//If multiple axis value tables have the same axis index, then one of the following should be true:
// The font is a variable font, and the axis is defined in the font variations table as a variation.
// The OlderSiblingFontAttribute flag is set in one of the records.
//Two different fonts within a family may share certain style attributes in common.
//For example, Bold Condensed and Bold Semi Condensed fonts both have the same weight attribute, Bold.
//Axis value tables for particular values should be implemented consistently across a family.
//If they are not consistent, applications may exhibit unpredictable behaviors.
