html5 - HTML 5 - Do I need to declare DOCTYPE on includes and pages with decorator -

-

i'm using struts 2 , working through pages make them html 5 compliant.

all pages using single decorator jsp declared in decorators.xml

the decorator.jsp includes first line:

<!doctype html>

do need declare first line on pages (specified in struts.xml) <!doctype html> on these?

if yes, need same <s:include />ed pages?

the doctype declaration should first line of html document rendered result. can place space characters, comments, or bom character before doctype. see conformant documents in html syntax. pages decorated in head or body of document doctype should before these tags , before tag. place doctype on every page @ first line, either included or manual, , use page decorator. doctype declaration should rendered once per html document, shouldn't include every page <s:include/>-ed in main page.

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
