turtle parser fails on prefixed symbols containing '.'

Description

Uploading a Turtle file containing prefixed URIs with '.' incorrectly complains.

For example, loading

@prefix : <http://example.com/> .
:sym.1 a :symbol .

produces the error "Malformed document: Illegal predicate value: ".1"^^http://www.w3.org/2001/XMLSchema#decimal". Using the same example, but ":sym1" rather than ":sym.1", loads correctly. The error also occurs with URIs like "foo:sym.1".

I believe these are valid URIs according to the spec (and Redland's Rapper handles them).

AFAIKT, the turtle grammar does not allow dots (0x2E) in qnames, making a qname like ":sym.1" invalid.

Hmm, you're right: i must have misread the grammar (or been fooled by Rapper). Sorry for the noise: this is not a bug.
