mtlcl410andClaude Opus 5.5 afdb368051 M12: XFA repeating subforms lay out more than 50 rows ...

A repeating subform laid out at most 50 instances, so rows 51 and on of a
long list or table (from the data, or added by a button's addInstance)
were left out. XFA 3.3, "The occur element" (p. 786): max -1 sets no
upper boundary.

The per-subform bound is now 1,000: the largest occur count the parser
reads and the most rows one script run may add (MAX_ADDED). The layout
budgets still bound the whole form. Opening a form with 1,000 one-field
rows takes about 3 s in a debug build and 2,000 rows about 13 s, so a
much larger bound would let one list stall the app. Rows past the occur
max or the bound are still reported, and the warning now names the
layout's bound when that is what cut them.
