[dthaler]

Typos / grammar

• Line 5: “the two format's conceptual models” → “the two formats’ conceptual models” (or rephrase)
• Line 23: “associate people with and g7:record-FAM …” → remove “and”; e.g. “associate people with a g7:record-FAM …”
• Line 26: “it's UI” → “its UI”
• Line 26: g7:recrd-FAM → g7:record-FAM
• Line 62: “correpsonds” → “corresponds”
• Line 62: “impore” → likely “import” (or “map”), depending on intended meaning
• Line 62: “convering” → “converting”
• Line 76: “prolypic Gregorian calendar” → “proleptic Gregorian calendar”

Likely directionality mixups (GX-to-G7 vs G7-to-GX)

• Line 30 (PHRASE section): says “For G7-to-GX … we can create g7:PHRASE …”
  This seems reversed: creating g7:PHRASE would be an output decision for GX-to-G7, not G7-to-GX (or should be reworded to clarify dropping/mapping behavior).
• Line 50 (Negative assertions section): “For G7-to-GX … we simply don’t create g7:NO or g7:FAMC-STAT structures.”
  Also appears directionally reversed or needs clarification (since g7:NO/g7:FAMC-STAT are G7 constructs).
