A conforming file shall not contain any reference XObjects
The document contains a reference XObject (Ref key in the form XObject dictionary)
Reference XObjects enable one PDF document to import content from another. The document in which the reference occurs is called the containing document; the one whose content is being imported is the target document.

For any given composite (Type 0) font within a conforming file, the CIDSystemInfo entry in its CIDFont dictionary and its Encoding dictionary shall have the following relationship:
- If the Encoding key in the Type 0 font dictionary is Identity-H or Identity-V, any values of Registry, Ordering, and Supplement may be used in the CIDSystemInfo entry of the CIDFont.
- Otherwise, the corresponding Registry and Ordering strings in both CIDSystemInfo dictionaries shall be identical, and the value of the Supplement key in the CIDSystemInfo dictionary of the CIDFont shall be less than or equal to the Supplement key in the CIDSystemInfo dictionary of the CMap.
CIDSystemInfo entries the CIDFont and CMap dictionaries of a Type 0 font are not compatible
CIDFont and CMap dictionaries contain a CIDSystemInfo entry specifying the character collection assumed by the CIDFont or by each CIDFont associated with the CMap - that is, the interpretation of the CID numbers used by the CIDFont. A character collection is uniquely identified by the Registry, Ordering, and Supplement entries in the CIDSystemInfo dictionary. Character collections whose Registry and Ordering values are the same are compatible.
PDF/UA-1 standard requires that the Registry and Ordering strings of the CIDSystemInfo dictionaries for that font shall be identical and the value of the Supplement key in the CIDSystemInfo dictionary of the CIDFont shall be less than or equal to the Supplement key in the CIDSystemInfo dictionary of the CMap, unless the value of the CMap dictionary UserCMap key is "Identity-H" or "Identity-V".

ISO 32000-1:2008, 9.7.4, Table 117 requires that all embedded Type 2 CIDFonts in the CIDFont dictionary shall contain a CIDToGIDMap entry that shall be a stream mapping from CIDs to glyph indices or the name Identity, as described in ISO 32000-1:2008, 9.7.4, Table 117.
A Type 2 CIDFont dictionary has missing or invalid CIDToGIDMap entry
For Type 2, the CIDFont program is actually a TrueType font program, which has no native notion of CIDs. In a TrueType font program, glyph descriptions are identified by glyph index values. Glyph indices are internal to the font and are not defined consistently from one font to another. Instead, a TrueType font program contains a "cmap" table that provides mappings directly from character codes to glyph indices for one or more predefined encodings.
If the TrueType font program is embedded, the Type 2 CIDFont dictionary must contain a CIDToGIDMap entry that maps CIDs to the glyph indices for the appropriate glyph descriptions in that font program.

A CMap also specifies the writing mode (horizontal or vertical) for any CIDFont with which the CMap is combined. This determines which metrics are to be used when glyphs are painted from that font.
In case of embedded CMap file, the writing mode is specified in two different places: in the PDF dictionary associated with the embedded CMap, and inside the embedded CMap file itself. To avoid any ambiguities, PDF/A standard requires that values of these two writing modes coincide.

Embedded fonts shall define all glyphs referenced for rendering within the conforming file. A font referenced solely in text rendering mode 3 is not rendered and is thus exempt from the requirements that impact the visual representation of the glyphs of a font. In all cases for TrueType fonts that are to be rendered, character codes shall be able to be mapped to glyphs according to ISO 32000-1:2008, 9.6.6.4 without the use of a non-standard mapping chosen by the conforming processor.
Not all glyphs referenced for rendering are present in the embedded font program
All conforming PDF/UA readers shall use the embedded fonts, rather than other locally resident, substituted or simulated fonts, for rendering.
The fonts used exclusively with text rendering mode 3 (invisible) are exempt from this requirement. OCR solutions often use such invisible fonts on top of the original scanned image to enable selection and copying of recognized text.
There is no exemption from the requirements of this rule for the 14 standard Type 1 fonts. The PostScript names of 14 Type 1 fonts, known as the standard fonts, are as follows:
