Late to comment and not had time to fully investigate in detail. So
apologies if I have not appreciated a rationale already given. But I'm
having a hard time accepting some of the regex'es which seem to depart from
Rabin's work.


* Sect 2.1

Minor point but in the component diagram the "scheme" brace over extends and
includes the colon char (":") which is a delimiter and NOT part of the

* Table 4

I do not follow rationale for the regex's in the table. I agree with Rabin's
regex given earlier in Sect. 2.1.

Specifically I do not see why "\/\/" are listed as required components in
the regex which they're clearly not in Rabin's and clearly not required in a
generic URI.

E.g. the initial "schemes" regex is given as


The "\/\/" have nothing to do with URI scheme or delimiting URI scheme. That
job is done by the colon char (":") alone.

Likewise for remaining components, why is the "\/\/" exposed as a required
pattern when it should be part of the optional authority component?

* Sect 2.1.2

Again the template regex departs from Rabin's and makes the "\/\/" pattern
required. Which it shouldn't be for a generic URI.


* Sect 4.2, Text
* Table 3

Again regex has "\/\/" a required pattern. Surely that's not a requisite for
generic URI processing?

I see the rationale for including the "\/\/" in Examples 4-1, 4-2 where
their presence can be inferred form the "<includehosts>" element, and in
Examples 4-3, 4-4 from the "<includeuripattern>" content.
