Well to take the HCl example, I claim the Cl- ions do not carry a
little tag with them to tell you they were last bonded with an H+
vs. an Na+.  And CO3- ions do not have a marker to tell you whether
they came from H2CO3 or K2CO3.  So yes, they do count as "solids"
and an HCl solution does NOT have 0 TDS.
