[sv-bc] Is '1 allowed in a concatenation?

Is a literal like '1 allowed in a concatenation?

On the one hand, 11.4.12 says, "Unsized constant numbers shall not be allowed in concatenations. This is because the size of each operand in
the concatenation is needed to calculate the complete size of the concatenation."

On the other hand, 5.7.1 says, "An unsized single-bit value can be specified by preceding the single-bit value with an apostrophe ( ' ), but without the base specifier. All bits of the unsized value shall be set to the value of the specified bit. In a self-determined context, an unsized single-bit value shall have a width of 1 bit, and the value shall be treated as unsigned."

I tend to the interpretation that they are not allowed.
