This isn't the first time I encounter someone who thinks the 6-limit applies here somehow, so let me quote the exact sections relevant.
Baseline attributes range start at 1 and can go
up to 6. That range is modified by metatype and/
or chosen qualities.
In other words, the RANGE defaults to 1-6 but can be 1-X depending on circumstances. There's no limit of 'ma 6' on attribute points.
During character creation, only one attribute
may be at the maximum for the selected metatype
Each metatype
(except for human) has two or more attributes that
can be outside the base 1–6 range. These are the
special racial attributes, and they can be increased
with adjustment points from this column.
You can raise the attributes, not just the part outside the base range.
So if you're an Elf, you can put 6 Attribute Points into Charisma to raise it from 1 to 7. Or you can use 3 Attribute Points to raise it to 4, then 4 Adjustment Points to raise it further to 8. You're not limited to attribute points until 6 and adjustment points above that.
