MWTC,
I don't know what the codes stand for but from the standpoint of protein content, moisture content, and absorption rate, the French flour most closely mimics a low-protein all-purpose flour, perhaps something like a southern all-purpose flour, not one like the King Arthur all-purpose flour that has a protein content of 11.7%. But that doesn't mean that you can use a domestic all-purpose flour and expect the same results, for the reasons previously mentioned. The Honeyville flour you referenced has a higher protein content than the French 55 (more in the range of bread flour) and it has a higher absorption rate (63% vs. 57-59%).
