In the Entity section of the HTML 4.0 draft [1], the following two entries are listed (not next to each other): perp "⊥" up tack, =orthogonal to, =perpendicular, u+22A5 ISOtech and "⊥" logical and, =wedge, u+2227 ISOtech According to the Unicode page [2], "logical and" is indeed u+2227 and "up tack" is indeed u+22A5. However, these should have different numerical entities, am I right? I believe two Dec-to-Hex math conversion errors were made in this section: <!ENTITY ang CDATA "∠" -- angle, u+2220 ISOamso --> <!ENTITY and CDATA "⊥" -- logical and, =wedge, u+2227 ISOtech --> <!ENTITY or CDATA "⊦" -- logical or, =vee, u+2228 ISOtech --> <!ENTITY cap CDATA "∩" -- intersection, =cap, u+2229 ISOtech --> Assuming this is just straight Hex conversion, 8869 is equivalent to 22A5, which implies that the "and" entity should be 8743. Similarly, "or" should then be 8744, which fits with the number for the "cap" entry.
