Sorry, I should have been less terse. I meant that PCRE provides a more sophisticated RE engine.
Off topic, but why does the documented URI pattern not recognize fragments prefixed by "#"? -- Shmuel (Seymour J.)

No. It uses the C++ RTL ECMAScript Grammar which is 99% compatible with PCRE. AFAIK, the only thing it doesn't support is recursive subgroup matching which I could care less about.
