+<H2> Note on missing 'Mandatory' Tags</H2>
+
+Each time it's possible to assume a 'reasonable' default value for missing
+'mandatory' tag, gdcm does it. <br>
+For instance if the Tag 'Samples Per Pixels' is missing, we assume its value is
+'1' (Grey pixels, as opposite to RGB); if the tag 'High BIt' is missing, we
+assume its value is 'Bits stored -1' (i.e. : no bad trick inside the pixels)<br>
+As gdcm wants to read *as well* old ACR-NEMA files, it has to be widely
+tolreant.
